Answer 1

To simply find it ti is the last store.

Explanation:

Answer 2

The best deal is offered by the Store Z

Solution:

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

Store X: 4 cans for $2.48

Therefore, store X sells 4 cans for $ 2.48

Price of 1 can is found by dividing 2.48 by 4

`\text{Price of 1 can } = (2.48)/(4) = 0.62`

Thus unit rate of store X is $ 0.62 per can

Store Y: 5 cans for $3.00

Therefore, store Y sells 5 cans for $ 3.00

Price of 1 can is found by dividing 3.00 by 5

`\text{Price of 1 can } = (3)/(5) = 0.6`

Thus unit rate of store Y is $ 0.6 per can

Store Z: 59 cents per can

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

`0.62 > 0.6 > 0.59`

Thus, unit rate of store Z is lower than store Y and store X

Therefore, the best deal is offered by the Store Z
