Question

The electronics store is offering 30% off all accessories. If Lisa saves $9.00 buying four charging cords, what was the original price of the cords?

Answer 1

Cost of each cord = $7.5

Explanation:

Given:

Discount rate = 30% = 0.30

Amount save by Lisa = $9

Number of charger = 4

Find:

Cost of each cord

Computation:

Total cost of 4 charger = Amount save by Lisa[1/Discount rate]

Total cost of 4 charger = 9[1/0.30]

Total cost of 4 charger = $30

Cost of each cord = Total cost of 4 charger / Number of charger

Cost of each cord = $30 / 4

Cost of each cord = $7.5
