Here are the step-by-step solutions for each problem on the worksheet.
1. Leticia's Blankets
*
Step 1: Identify the numbers. Leticia sold 92 blankets, and each one costs $49.
*
Step 2: To find the total money made, multiply the number of blankets by the price of one blanket.
* Calculation: $92 \times 49$
*
Step 3: Do the math.
* $92 \times 40 = 3,680$
* $92 \times 9 = 828$
* $3,680 + 828 = 4,508$
*
Result: She made $4,508.
2. Peter's Chocolates
*
Step 1: Find the total number of square pieces. There are 70 chocolates, and each has 12 pieces.
* Calculation: $70 \times 12 = 840$ total pieces.
*
Step 2: Find out how many people are sharing. It is Peter plus his 11 cousins.
* Calculation: $1 + 11 = 12$ people.
*
Step 3: Divide the total pieces by the number of people to see how many each person gets.
* Calculation: $840 \div 12$
* $84 \div 12 = 7$, so $840 \div 12 = 70$.
*
Result: They each get 70 pieces.
3. The Mechanic's Cars
*
Step 1: Find out how many weeks are in 4 years. The problem says there are 52 weeks in a year.
* Calculation: $4 \times 52 = 208$ weeks.
*
Step 2: Multiply the total weeks by the number of cars serviced per week (14).
* Calculation: $208 \times 14$
*
Step 3: Do the math.
* $208 \times 10 = 2,080$
* $208 \times 4 = 832$
* $2,080 + 832 = 2,912$
*
Result: He services 2,912 cars.
4. Sheryl's School Trip
*
Step 1: Find the total number of passengers. Add the children, teachers, and parents together.
* Calculation: $171 + 22 + 13 = 206$ people.
*
Step 2: Determine how many buses are needed. Each bus holds 20 people. Divide the total people by the bus capacity.
* Calculation: $206 \div 20 = 10$ with a remainder of 6.
* This means 10 buses will be full, but there are still 6 people left over. You need one more bus for them.
* Total buses needed: $10 + 1 = 11$ buses.
*
Step 3: Calculate the spare seats.
* Total seats available on 11 buses: $11 \times 20 = 220$ seats.
* Subtract the number of people from the total seats: $220 - 206 = 14$ spare seats.
*
Result: She needs 11 buses, and there will be 14 spare seats.
Final Answer:
1. $4,508
2. 70 square pieces
3. 2,912 cars
4. 11 buses; 14 spare seats
