Question

Debra's penny bank is 7/10 full. After she removes 240 pennies, it is full. How many pennies can Debra's bank hold?

a) 600 pennies
b) 360 pennies
c) 400 pennies
d) 700 pennies

Answer 1

Debra's penny bank can hold 1680 pennies.

Step-by-step explanation:

To find out how many pennies Debra's bank can hold, we need to determine the amount of pennies that filled the remaining 3/10 of the bank after 240 pennies were removed.

Since the bank was originally 7/10 full, this means that the remaining 3/10 is equal to the 240 pennies. To find the number of pennies that the bank can hold, we can set up a proportion:

7/10 = x/240

Cross-multiplying, we get:

10 * x = 7 * 240

x = 1680/10 = 168

So, Debra's bank can hold 1680 pennies. The correct option is a) 600 pennies.
