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.

Respuesta :

We need to find the list price of 4 dozens

[tex]161\times4=644[/tex]

Then we need to calculate the series discount

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

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

[tex]644\cdot0.399=256.956[/tex]

he will pay $256.956 after the series discount
