Question

The cost is $8.50 for 1 shirt. How do you find the cost of 4 shirts?

Answer 1

The cost of 4 shirts is $34.00

Explanation:

A formula to express this relationship is:

`c = $8.50 xx s`

Where `c` is the cost and `s` is the number of shirts purchased.

We can substitute `4` for `s` to calculate the cost:

`c = $8.50 xx 4`

`c = $34.00`
