Mike is working on solving the exponential equation 37x = 12; however, he is not quite sure where to start. Solve the equation and use complete sentences to describe the steps to solve.
Hint: Use the change of base formula: log y =
log y
log b
Using logarithmic properties, what is the solution to log3(y + 5) + log36 = log366? Show all necessary steps.
4.2 Comparing Linear and Exponential Change
7) Money is added to (and never removed from) two different savings accounts (Account A
and Account B) at the start of each month according to different mathematical rules. Each
savings account had $500 in it last month and has $540 in it this month.
(a) Assume the money in Account A is growing linearly:
How much money will be in the account next month?
How much money was in the account two months ago?
How long will it take for the account to have at least $2500?
Write an equation relating the amount of money in the
account and the number of months from now. Clearly
define the meaning of each variable in your equation, and
interpret the meaning of each constant in your equation.
(b) Assume the money in Account B is growing exponentially.
How much money will be in the account next month?
How much money was in the account two months ago?
How long will it take for the account to have at least $2500?
Write an equation relating the amount of money…

Since 15% of $60 is $9, that means you increase your $60 by $9, so you now have $69. Notice that we did this calculation in two steps: first we multiplied $60 by 0.15 to find 15% of $60, then we added this amount to our original $60. Explain why it makes sense that increasing $60 by 15% can also be accomplished in one step by multiplying $60 times 1.15. 3) Suppose you have $60 and want to decrease this amount by 15%. Since 15% of $60 is $9, that means you will decrease your $60 by $9, so you now have $51. Notice that we did this calculation in two steps: first we multiplied $60 by 0.15 to find 15% of $60, then we subtracted this amount from our original $60. Explain why it makes sense that decreasing $60 by 15% can also be accomplished in one step by multiplying $60 times 0.85. 4) In the Read and Study section, we noted that the population in Colony B is increasing each year by 25%.

Does it matter if you take off the coupon first or add in the tax first? 6) You have ten coupons that allow you to take 10% off the sales price of a jacket, and for some strange reason, the store is going to allow you to use all ten coupons! Does this mean you get the jacket for free? Let's really think about what would happen at the checkout. First, the teller would scan the price tag on the jacket, and the computer would show the price is $100. After the teller scans the first coupon, the computer will take 10% off of $100, and show the price is $90. (Right? Think about why this is.) Then after the teller scans the second coupon, the computer will take 10% off of $90. (a) Continue this reasoning to fill in the table below showing the price of the jacket (y) after you apply x coupons. (b) Make a graph showing the price of the jacket from x = 0 to x = 10 coupons applied.…arrow_forward
