Here are the step-by-step solutions for each word problem on the worksheet.
Problem 1
*
Goal: Find out how many items were made this year.
*
Given: The usual amount is 500,000. This year, they made 155,988 *less* than that.
*
Math: We need to subtract the difference from the total.
$$500,000 - 155,988$$
*
Calculation:
* $500,000 - 100,000 = 400,000$
* $400,000 - 55,988 = 344,012$
*
Result: 344,012 items.
Problem 2
*
Goal: Find out how much more money is needed.
*
Given: The house costs $\$738,220$. You already have $\$539,250$.
*
Math: Subtract the money you have from the total cost.
$$\$738,220 - \$539,250$$
*
Calculation:
* $738,220 - 539,250 = 198,970$
*
Result: $\$198,970$
Problem 3
*
Goal: Find the difference in earnings between Simon and Jimmy.
*
Given: Simon earns $\$382,000$. Jimmy earns $\$117,222$.
*
Math: Subtract Jimmy's earnings from Simon's earnings.
$$\$382,000 - \$117,222$$
*
Calculation:
* $382,000 - 117,222 = 264,778$
*
Result: $\$264,778$
Problem 4
*
Goal: Find out how much money Mr. Chapel saved.
*
Given: He earned $\$377,930$. His expenses were $\$218,500$.
*
Math: Subtract expenses from earnings to find savings.
$$\$377,930 - \$218,500$$
*
Calculation:
* $377,930 - 218,500 = 159,430$
*
Result: $\$159,430$
Problem 5
*
Goal: Find what number must be added to 296,451 to get 649,450.
*
Given: Start number is 296,451. End number is 649,450.
*
Math: To find the missing part, subtract the start number from the end number.
$$649,450 - 296,451$$
*
Calculation:
* $649,450 - 296,451 = 352,999$
*
Check: $296,451 + 352,999 = 649,450$. The math is correct.
*
Result: 352,999
