Recall the property of parallelograms that tell us that the diagonals intercept producing equal segments in each of them. Then, as the diagonals intercept in the midpoint of each diagonal, then we can create the following equations and solve them one at a time (making the measure of one segment equal the value on the other half of the diagonal):

5 y - 4 = 36 then we solve here for y

add 4 to both sides

5 y = 36 + 4

5 y = 40

divide both sides by 5

y = 40 / 5

y = 8

Now the second equation:

4 x - 10 = 18

add 10 on both sides

4 x = 28

divide both sides by 4 to isolate x

x = 28 / 4

x = 7

#1 - HINT - you are finding the total amount make sure you add the interest you calculate to the original deposit amount
Andreyy89

Answer:

$292.50

Step-by-step explanation:

Equation - A = P(1 + rt)

Calculation:

First, converting R percent to r a decimal

r = R/100 = 2.5%/100 = 0.025 per year.

Solving our equation:

A = 260(1 + (0.025 × 5)) = 292.5

A = $292.50

The total amount accrued, principal plus interest, from simple interest on a principal of $260.00 at a rate of 2.5% per year for 5 years is $292.50.
