Question

Yolanda's penny bank is 3/4 full. After she removes 280 pennies, it is 1/2 full. How many pennies can Yolanda's bank hold?

Answer 1

We now that the bank is 3/4 full after she removes a part is 1/2 full, so the parte that she removes is

`(3)/(4)-(1)/(2)=(1)/(4)`

this means that 280 pennies is 1/4 of the bank. This means that the bank can hold for times this amount, this means 1120 pennies.

`280\cdot4=1120`

The answer is 1120 pennies.
