Question

Jan wants to collect $1. But she has 2 quarters, 2 dimes, and 4 nickels. She needs pennies more.

• A. 15
• B. 20
• C. 10

Answer 1

The correct option is C 10

$1 = 100 cent
Jan already has 2 quarters, 2 dimes, and 4 nickels
2 $\times$ 25 = 50 cents
2 $\times$ 10 = 20 cents
4 $\times$ 5 = 20 cents
Total = 50 + 20 + 20 = 90 cents
She needs 10 cents more
1 cent = 1 penny
So, she has to collect 10 more pennies to make it $1.
