is there a typo in your formula? where is the "w" ?

Answer 2

oh yeah 2.33w

Answer 3

like this
c=2.33w+14.23
?

Answer 4

yes

Answer 5

2.33w is short for 2.33 times w. If you know what w is, you can do the arithmetic.

when they tell you the weight is 3 pounds, that means w = 3 and you can do the multiplication

to answer
c=2.33w+14.23
when w=3, replace the w with 3, multiply, and then add 14.23
