Answer:
Part A: $60
Part B: $54
Step-by-step explanation:
First step is parentheses so subtract 1/4 from 1
(1-1/4) = (4/4 - 1/4) = (3/4)
After parentheses we perform exponent operations
(3/4)^2 = (3^2/4^2) = (9/16)
Finally, after exponent operations we perform multiplications
(1/3)*(9/16) = (3/16)
3 dimes, 1 nickel
2 dimes, 3 nickels
1 dime, 5 nickels
7 nickels
(don't forget to add in the initial quarter, dime, and nickel)
