Apackage of 3 fruit bars costs $1.65 a package of 5 fruit bars costs $2.40 is the price of a package of fruit bars proportional to the number of fruit bars in the package

No, the price of a package of fruit bar is not proportional

= 5

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
