To find: the numbers according to the given system of equation.

Answer to Problem 41PPS
Explanation of Solution
Given:
Twice the sum of a number and three times a second number is 4.
And the difference of ten times the second number and five times the first number is 90.
Calculation:
Let the first number be x and second number be y .
According to the question,
Since none of the expressions is same on both the equation, therefore multiply by 5 in 1st equation and multiply by 2 in 2nd equation and then equate:
Now, subtract the equation
Now, substitutes the value of y in 2nd equation, then:
Hence, numbers according to the given system of equation is

Based on historical observations, Gary has gathered the following data, which show the numbers of these coffees sold over six different price values: Price Number Sold $2.70 765 $3.50 515 $2.00 990 $4.30 240 $3.10 325 $4.00 475 Using simple linear regression and given that the price per cup is $1.85, the forecasted demand for mocha latte coffees will be cups (enter your response rounded to one decimal place).arrow_forward
