Problem 1:
Johnson makes toy cars. He wants to make 1,500. Johnson can make 18 cars a day. He has already made 492. How many days will it take him to get to 1,500?
####
Step-by-step Solution:
- Total cars Johnson wants to make:
1,500
- Cars already made:
492
- Remaining cars to make:
$ 1,500 - 492 = 1,008 $
- Cars he can make per day:
18
- Days needed:
$ 1,008 ÷ 18 = 56 $
✔ Answer: 56 days

Problem 2:
Bill and his 3 friends read 55 books each for the year. Each book had an average of 320 pages. How many pages did they all read in total that year?
####
Step-by-step Solution:
- Number of people: Bill + 3 friends =
4 people
- Books per person:
55
- Total books read by all:
$ 4 × 55 = 220 $ books
- Pages per book:
320
- Total pages read:
$ 220 × 320 = 70,400 $
✔ Answer: 70,400 pages

Problem 3:
Mary is having a birthday party. She invited 14 friends. Mary made 190 cookies. She wants to share them at her party but also wants to save 22 for her mother and father. How many cookies will each person get at the party?
####
Step-by-step Solution:
- Total cookies made:
190
- Cookies saved for parents:
22
- Cookies available for the party:
$ 190 - 22 = 168 $
- People at the party: Mary + 14 friends =
15 people
- Cookies per person:
$ 168 ÷ 15 = 11.2 $
But since we can't split a cookie into decimals in real life (unless specified), let’s check if it divides evenly:
- $ 15 × 11 = 165 $ → leaves 3 extra cookies
- So, each person gets
11 cookies, with
3 left over
However, the question asks “how many cookies will each person get?” — assuming equal sharing, we can say:
✔ Answer: 11 cookies each (with 3 leftover)
Alternatively, if fractional cookies are allowed:
11.2 cookies per person
But typically in such problems, whole numbers are expected.
✔ Best answer: 11 cookies each

- Cards per friend:
$ 624 ÷ 12 = 52 $
✔ Answer: 52 cards each
