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.
[tex](x-\$0.55)\times6=\$8.70[/tex]Now let us solve this equation for x.
[tex]\begin{gathered} (x-\$0.55)\times6=\$8.70 \\ 6x-\$3.3=\$8.70 \\ 6x=\$8.70+\$3.3 \\ 6x=\$12 \\ x=\frac{\$12}{6} \\ x=\$2 \end{gathered}[/tex]Therefore, the regular price of each gallon of fruit punch is $2
