Question

A youth league soccer coach needs to buy 4 dozen soccer balls. The list price is $161 per dozen and a series discount of 40 / 5 / 30 is offered. Find how many the coach will pay for the soccer balls.

Answer 1

We need to find the list price of 4 dozens

$161\times4=644$

Then we need to calculate the series discount

$\begin{gathered} (1-0.4)\times(1-0.05)\times(1-0.3) \\ 0.6\times0.95\times.7=0.399 \end{gathered}$

Then we calculated how much the coach will pay for the 4 dozen

$644\cdot0.399=256.956$

he will pay $256.956 after the series discount
