Here are the step-by-step solutions for each problem on the worksheet.
Problem i
1. First, find out how much tape was cut off in total. There were 4 pieces cut, and each was 4.25 feet long.
$4 \times 4.25 = 17$ feet.
2. Subtract the amount cut from the original length of the tape (20 feet).
$20 - 17 = 3$ feet.
Problem ii
1. To find the cost of one gallon, divide the total price paid ($22.44) by the number of gallons (4).
2. $22.44 \div 4 = 5.61$.
Problem iii
1. Start with the initial balance: $945.82.
2. Add the deposit amount: $945.82 + 75.75 = 1021.57$.
3. Subtract the withdrawal amount from that new total: $1021.57 - 265.40 = 756.17$.
Problem iv
1. Calculate the cost of the cups: 12 cups $\times$ $2.25 each = $27.00.
2. Calculate the cost of the plates: 6 plates $\times$ $5.75 each = $34.50.
3. Calculate the cost of the bowls: 6 bowls $\times$ $3.00 each = $18.00.
4. Add all the costs together to find the total: $27.00 + 34.50 + 18.00 = 79.50$.
Final Answer:
i. 3 feet
ii. $5.61
iii. $756.17
iv. $79.50
