The best deal is offered by the Store Z
<em><u>Solution:</u></em>
We have to find which store offers the best deal
This is found by calculating the unit rate of each store
Unit rate of each store means price per can .i.e price of 1 can
<h3><u>Store X: 4 cans for $2.48</u></h3>Therefore, store X sells 4 cans for $ 2.48
Price of 1 can is found by dividing 2.48 by 4
Thus unit rate of store X is $ 0.62 per can
<h3><u>Store Y: 5 cans for $3.00</u></h3>Therefore, store Y sells 5 cans for $ 3.00
Price of 1 can is found by dividing 3.00 by 5
Thus unit rate of store Y is $ 0.6 per can
<h3><u>Store Z: 59 cents per can</u></h3>1 cents is equal to 0.01 dollar.
59 cents = 0.59 dollar
Thus unit rate of store Z is $ 0.59 per can
Comparing unit rate of store X, Y, Z
Thus, unit rate of store Z is lower than store Y and store X
Therefore, the best deal is offered by the Store Z
