Answer
$305 hope this helps!!! :)
Step-by-step explanation:
(A)
Let [tex]x[/tex] be the number of T-Shirts and [tex]y[/tex] be the total costs so that the total cost is:
Total Cost= $25+ $8 times the number of T-Shirts
(B) [tex]y=25+8x[/tex]
For 35 members we need 35 T-Shirts so using the Linear model from part (A) substitute [tex]x[/tex] to 35 and solve for [tex]y[/tex]:
[tex]y=25+8(35)[/tex]
[tex]y=25+280[/tex]
[tex]y=305[/tex]
