Question

F = –2s + 18 The variable s represents the number of shirts Vera has sewn, and the variable f represents the number of yards of fabric remaining. How many shirts can Vera sew, at most, and still have 10 yards of fabric left?

Answer 1

4 shirts.

Explanation:

We have been given an equation
`F =-2s + 18`, where the variable s represents the number of shirts Vera has sewn, and the variable f represents the number of yards of fabric remaining.

To find the number of shirts that Vera can sew and still have 10 yards of fabric left, we will substitute
`F = 10` and solve for s as:

`10 =-2s + 18`

Switch sides:

`-2s+18=10`

`-2s+18-18=10-18`

`-2s=-8`

`(-2s)/(-2)=(-8)/(-2)`

`s=4`

Therefore, Vera can sew 4 shirts at most and still have 10 yards of fabric left.
