Question

Specially T-Shirts are being sold online for $30 plus a one time handling fee of $2.75. The total cost is a function of the number of T-shirts bought. What function rule models the cost of the T-shirts? Evaluate the function for 5 T-shirts.

Answer 1

2.75 is a one-time fee, so you only put that once. And 30 is charged for each shirt, x amount of shirts. So what do you think the equation would be?

Answer 2

2.75+30x

Answer 3

Yep. Then you put 5 in for x.

Answer 4

30*5 + 2.75

Answer 5

152.75

Answer 6

Can I ask you another question?

Answer 7

Sure :P

Answer 8

Thanks! :) The distance walking a marathon at a constant speed is directly proportional to the time of walking. If Jennifer walked 9 miles in 3 hours, how many miles will Jennifer walk in 5 hours at the same constant speed?

Answer 9

You need to set up a proportion I think. distance/time
