DIMES: 5 Quarters: 8
Step-by-step explanation:
She could have 5 dimes because we know 1 dime is 10 cents,and we know 5*10=50. And we can have 8 quarters because we know 4 quarters is $1.00,and 8 quarters would be $2.00. 2.00+.50=2.50.
Answer:
13/8
Step-by-step explanation:
let the number be x
5/8 - x = -1
-x = -1 - 5/8
-x = - 13/8
x = 13/8
5/8- 13/8 = -1
The answer is $25.35
6.96× 3= 20.85
20.85+ 4.50= $25.35
