Azul bought 10 reams of paper at the store for a total of $84. The tax on the purchase was $4. What was the cost of each ream of paper. Equation

Respuesta :

it is 8.40 if your not including tax and 8.80 if your are
Subtracting $4 from $84 gives us the pre-tax price:  $80.

Thus, the unit cost of the reams of paper would be $80/10, or $8.
