Jenna bought 5 reams of paper at the store for a total of $21 . The tax on her purchase was $1 . Write a equation and solve to find the price of each ream of paper

Answer:The equation needed is [tex]\textrm{Cost of 1 ream of paper}  =  \frac{20}{5} [/tex]The cost per ream of paper  = $4Step-by-step explanation:Here, the cost of 5 reams of paper  = $ 21The tax on her purchase  = $1So, the actual cost of 5 reams of paper  = Total Cost paid  - Tax amount = $ 21 -  $ 1  = $20So, the actual cost of 5 reams of the paper is $20.Now, to find out the cost of 1 ream of paper:[tex]\textrm{Cost of 1 ream of paper}  = \frac{\textrm{Total amount paid for 5 reams}}{\textrm{ 5}}  \\= \frac{20}{5}  = 4[/tex]=  $4Hence, the cost of each ream of paper  = $ 4.
