Answer:
4 shirts.
Step-by-step explanation:
We have been given an equation [tex]F =-2s + 18[/tex], 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 [tex]F = 10[/tex] and solve for s as:
[tex]10 =-2s + 18[/tex]
Switch sides:
[tex]-2s+18=10[/tex]
[tex]-2s+18-18=10-18[/tex]
[tex]-2s=-8[/tex]
[tex]\frac{-2s}{-2}=\frac{-8}{-2}[/tex]
[tex]s=4[/tex]
Therefore, Vera can sew 4 shirts at most and still have 10 yards of fabric left.
