UNIT 2: WORD PROBLEM WORKSHEET
The equation C(r) = 4 r + 10 represents thecost C(r) at the county fair based on the
number of rides, r.
(a.) Jake has $ 18 in his pocket. How manyrides can he go on?
4 r + 10 = 18- 10 - 10
4 r = 8
4 4
r = 2

UNIT 2: WORD PROBLEM WORKSHEET
The equation C(r) = 4 r + 10 represents thecost C(r) at the county fair based on the
number of rides, r.
(b.) If Jake wants to ride 10 rides, howmuch money does he have to borrow
from his friends?
4 (10) + 10 = C (r)
40 + 10 = C (r)50 = C (r)
50 – 18 = amt. to borrow
32 = amt. to borrow

The cost of a pizza is based on thenumber of toppings plus $ 8. The cost of a
5-topping pizza is $ 14.25. How much would a 3-topping pizza cost?
Let x = cost of one topping
5 x + 8 = 14.25- 8 - 8
5 x = 6.25
5 5
x = 1.25 = cost of one topping
3 (1.25) + 8 = 3.75 + 8 = 11.75= cost of 3-topping pizza

UNIT 2: WORD PROBLEM WORKSHEET
Find the mistake (if any) in the following problem: Then solve
it correctly.
- 2 ( x – 2) – 3 x = 10 + 5 x- 2 x + 4 – 3 x = 10 + 5 x
0 x + 4 = 10
- 5 x + 4 = 10 + 5 x
0 = 6 No solution
