Answer 1

Zak buys 6 gallons of fruit punch.

He has coupons for $0.55 off the regular price of each gallon of fruit punch.

This means that $0.55 will be subtracted from the regular price of each gallon.

After using the coupons, the total cost of the fruit punch is $8.70.

Let x be the regular price of each gallon of fruit punch.

`(x-\$0.55)*6=\$8.70`

Now let us solve this equation for x.

`\begin{gathered} (x-\$0.55)*6=\$8.70 \\ 6x-\$3.3=\$8.70 \\ 6x=\$8.70+\$3.3 \\ 6x=\$12 \\ x=(\$12)/(6) \\ x=\$2 \end{gathered}`

Therefore, the regular price of each gallon of fruit punch is $2
