Of you give me the equation I can probably solve it but I can't figure it out PLZ HELP!!!

($4.30 × 3)(3c) = $19.50

c = $2.20

Step-by-step explanation:

($4.30 × 3)(3c) = $19.50

(12.90)(3c) = 19.50

3c = 6.60

c = 2.20

(u had most of the equation laid out already, u were just missing 3c)

the graph in the attached figure

step-by-step explanation:

we have

using a graphing tool

the graph in the attached figure

the roots are ( x-intercepts) x=-0.5,x=1,x=3

the y-intercept is the point (0,3)

x is the total time in minutes for the free response

you are given number of questions as 15 - m and time per item as 8 minutes

to find x multiply the two givens together:

x = 8 * (15-m) = 8(15-m)
