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.

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers

trapezoid

step-by-step explanation:

first i plotted all my points on a grid graph

i made sure all of them were in the correct quadrant

then i saw it was a trapezoid or a quadrilateral
