Answer: CURRENT AGES: C = 35, D = 5 AGES IN 5 YEARS TIME: C = 40, D = 10
Step-by-step explanation:
We need to use algebra here.
Let C = Coffee's age
Let D = Daughter's age
C = 7 x D
C + 5 = 4 x (D + 5)
C + 5 = 20 + 4D
C = 15 + 4D
7D = 15 + 4D
D = 5
C = 7 x 5
C = 35
Your equation would be 179.35+218c=t, c=credit hours and t=total cost
make a T chart/table and use numbers to plug into c, to solve for t. Then graph using (c,t) as your coordinates. I hope this helps.
