Answer 1

Part 1) The equation that could be used to find x is

`12.25x+3.99=77.49`

Part 2) The value of x is

`x=6\ shirts`

Explanation:

Let

x-----> the number of shirts

we know that

The linear equation that represent the situation is

`12.25x+3.99=77.49`

Solve for x

Subtract 3.99 from both sides

`12.25x=77.49-3.99`

`12.25x=73.50`

`x=73.50/12.25`

`x=6\ shirts`
