Yanni has $0.85. His mother gave him $0.40 in addition. While going to the mall, Yanni found $0.50. He bought a toy that cost $1.6. How much money in cents did Yanni have left?
Step-by-step reasoning:
15
Yanni's mother gave him $0.

40 in addition to $0.

85 for a total of $0.

40 + $0.

85 = $1.

25.

Yanni found $0.

50 so he had a total of $1.

25 + $0.

50 = $1.

75.

Therefore, Yanni had $1.

75 - $1.

6 = $0.

15 left.

100 cents make $1 so $0.

15 is 100 * 0.

15 = 15 cents.

.

The final answer: 15
