Let’s solve each problem one by one, step by step.

Problem 1:
Leticia sold 92 blankets.
Each blanket costs $49.
To find how much she made, multiply:
92 × 49
Let’s break it down:
We can do 90 × 49 + 2 × 49
90 × 49 = (90 × 50) - (90 × 1) = 4500 - 90 = 4410
2 × 49 = 98
Now add: 4410 + 98 =
4508
✔ So, Leticia made
$4,508

Problem 2:
Peter has a box of 70 chocolates.
Each chocolate has 12 square pieces.
Total pieces = 70 × 12
70 × 12 = 840 pieces
He wants to split them between himself and his 11 cousins → that’s 1 + 11 =
12 people
So, divide total pieces by number of people:
840 ÷ 12
Let’s calculate:
12 × 70 = 840 → so 840 ÷ 12 =
70
✔ Each person gets
70 square pieces

Problem 3:
Mechanic services 14 cars per week.
There are 52 weeks in a year.
He works for 4 years.
First, find cars per year:
14 × 52
Break it down:
10 × 52 = 520
4 × 52 = 208
Add: 520 + 208 = 728 cars per year
Now for 4 years:
728 × 4
700 × 4 = 2800
28 × 4 = 112
Add: 2800 + 112 =
2912
✔ He services
2,912 cars over 4 years.

Problem 4:
Sheryl is organizing buses.
People going on trip:
- Children: 171
- Teachers: 22
- Parents: 13
Total passengers = 171 + 22 + 13
171 + 22 = 193
193 + 13 =
206 people
Each bus holds 20 passengers.
How many buses needed? Divide 206 by 20.
206 ÷ 20 = 10 with remainder 6
That means 10 full buses hold 200 people, and 6 people need another bus.
So, she needs
11 buses.
Spare seats for luggage: In the last bus, only 6 seats are used → 20 - 6 =
14 spare seats
✔ She needs
11 buses, and there will be
14 spare seats left for extra luggage.

Final Answer:
1. $4,508
2. 70 square pieces
3. 2,912 cars
4. 11 buses and 14 spare seats
