klasskru [66]

Answer:

The money he can save by buying them at Big 5 is $76.80.

Step-by-step explanation:

Given:

Footballs sell for $27.99 each at Sporting Goods.

Footballs sell for $21.59 each at Big 5.

The coach buys a dozen footballs.

Now, to find the amount he save by buying them at Big 5.

So, first we find the cost of footballs at Sporting Goods and at Big 5.

1 Dozen = 12 pieces.

Thus, the cost of footballs at Sporting Goods =

\$27.99\times 12 =\$335.88

And, the cost of footballs at Big 5 =

\$21.59\times 12=\$259.08.

Now, to get the amount coach can save by buying them at Big 5, we subtract both the cost as the cost of Sporting Goods is more than the Cost of Big 5:

The amount coach can save by buying them at Big 5 =

\$335.88-\$259.08=\$76.80.

Therefore, the amount he can save by buying them at Big 5 is $76.80.
