A corporation agrees to invest RO 10000 on radio, newspaper, and television advertising to market its goods. If he spends as much on TV advertising as two times on radio, and the amount spent on newspapers and TV combined equals four times that spent on radio. Given information leads to a system of linear equation x+y+z =10000 2x - z = 0 4x – y - z = 0 Using row reduction method, calculate the amount to be spent on each type of advertising.

Abigail Henderson has $3440.00 budgeted for spending money on an upcoming trip to Country A and Country B. Country A's currency is trading at $1.40 per currency A, and Country B's currency is trading at $1.60 per currency B. She plans to spend more time in Country A, so she wants to have five times as much of currency A as currency B. Set up and solve a system of equations to model this problem, and explain what the answer means in practical terms. Complete the equation that represents the total cost of purchasing currency. Let x be the number of currency A and y the number of currency B. = 3440.00 (Do not include the $ symbol in your answers. Do not simplify. Use integers or decimals for any numbers in the equation.)

Kelly Fisher has a total of $40,000 invested in two municipal bonds that have yields of 7% (bond A) and 9% (bond B) interest per year, respectively. If the interest Kelly receives from the bonds in a year is $3,440, how much did she invest in each bond? Formulate a system of equations that can be used to find the solution where x is the number of dollars invested in bond A and y is the number of dollars invested in bond B.
