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?

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.
