1) the marching bad is selling cases of fruit for $11 a case. Write an algebraic expression for the total sales in dollars of c case.

2) your job pays $7 per hour. Write an algebraic expression for your pay in dollars for working h hours
i wrote: $7(h)
are these correct?
Yup, they're correct, but for number one they ask you to use the variable c to represent the number of cases. So I would rewrite it as 11c
thanks was a typing error
thanks
Determine whether y varies directly with x in
6x 2 3 5 2y 2 3. If so, what is the constant of variation?
Yes, you are correct on both expressions.
1) The algebraic expression for the total sales in dollars for c cases of fruit is $11c. This is because each case costs $11, and you multiply that price by the number of cases (c) to get the total sales in dollars.
2) The algebraic expression for your pay in dollars for working h hours is $7h. This is because your hourly rate is $7, and you multiply that rate by the number of hours (h) worked to calculate your pay in dollars.
