Answer:
16 hours for an amount of $50
Step-by-step explanation:
The question did not specify how much Carmen has
but say he has $50
Step one:
Given data
Charge= $2
Cost per hour= $3
let x be the number of hours
the total can be modeled as
y=mx+c
50=3x+2
50-2=3x
48=3x
x=48/3
x=16hours
you can try out any amount using the expression
y=mx+c
