Question

Two dozen ping pong balls and four badminton shuttlecocks are to be purchased for a playground. The ping pong balls are priced at $0.35 each and the shuttlecocks $2.75 each. The playground receives a discount of 30% from these prices. Which of the following equals the total cost of this equipment?

Answer 1

To find the total cost of the equipment, you can calculate the actual cost of the materials and then apply the discount.

1. Cost of ping pong ball + cost of shuttlecocks

(0.35 x 24) + (2.75 x 4)

$19.40

2. 100% - 30% discount = 70% of it you are actually paying for. Change the percent to a decimal to calculate

0.70 x $19.40 = $13.58

The cost will be $13.58.
