Formulate but do not solve the problem. michael perez deposited a total of $2000 with two savings institutions. one pays interest at a rate of 5%/year, whereas the other pays interest at a rate of 8%/year. if michael earned a total of $130 in interest during a single year, how much did he deposit in each institution? (let x and y denote the amount of money, in dollars, invested at 5% and 8%, respectively.) 0.06x 0.08yx130 x2000

Step-by-step explanation:

Michael Perez deposited a total of $2,000 with two savings institutions.

One pays interest at a rate of 5% per year whereas the other pays interest at a rate of 8% per year.

Let x denote the amount of money invested at 5%

y = 2000 - x ---(1)

Let y denote the amount of money invested at 8%

so 5x/100 + 8(2000-x)/100 = $130 (2)

Michael earned $130 in interest during a single year.

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
