Answer:18

Step-by-step explanation:Well you know that there are 100 bricks on each side, subtract 28 from 10. It is still even and you are left with the boxes. 4 boxes has 72 bricks, so you divide that by four to get how many bricks each box has, leaving you with 18.

Tahmar knows the formula for simple interest is I = Prt, where I represents the simple interest on an amount of money, P, for t
frez [133]
The formula to find the simple interest earned is
I = Prt
Solve for p by dividing both sides by rt to get
P=I/rt
P=?
I=20
R=0.05
T=5years
So
P=20÷(0.05×5)
P=80

Hope it helps!
