Write two equations. Substitute 5 for x in one equation. Substitute 8 for x in the other equation.
what is 6 times 8 minus 80
what is 6 times 5 minus 80
subtract the second amount from the first, I get
6(8-5)

6(8-5)
Ok so will it look like this then?
y = 30 + 80
y= 48 + 80
And the answer would be $18?
y = 30 + 80
y= 48 + 80
And the answer would be $18?
correct answer.
