Suppose a rectangular house's length is 22 feet and its perimeter is 25 1/3 yards. How wide is it?
Explanation:
You can first convert the perimeter measurement to feet. 25 1/3 yards are similar to 76 feet when multiplied by three. Consequently, the equation shown below can be written: The equation 76 = 2(22) + 2w can be written as 76 = 44 + 2w, where w = 16. The house is 16 feet wide.
Lisa's base pay is $90 per week, and she also gets a 12% commission on all purchases. This week, Lisa brought in $3,000 in sales. How much money did she make overall?
Explanation:
The equation 90 + 0.12x, where x is the number of sales, can be used to show how much money she made. When 3000 is substituted for x, 90 + 0.12(3000) equals 450. Therefore, she earned $450 this week.
In a recipe for cookies, which of the following units should be used to measure the sugar?

John sold a yacht that he had himself designed for a 15% profit after paying $15,000 for it. How much was the boat sold for?
Explanation:
The equation 15,000 + 0.15(15,000), which equals 17,250, can be used to simulate the issue. So, he received $17,250 for the yacht.
All students receive a 10% reduction from the original instrument price from a music supply outlet. Back-to-school sales typically subtract an additional 15% from the already-discounted price. Mary, a high school student in the area, spends $306 on a flute. How much did it cost at first?
Explanation:
The issue can be resolved using the equation x-0.10x-0.15(x-0.10x)=306.
When x is solved for, 0.90x - 0.15x + 0.015x = 306 is obtained, where x = 400.
Consequently, the initial cost was $400.
How much money did Jane save in May 2001 if she only used 20% of the allotted amount for food rather than the full 25%?
Explanation:
She saved $131.10, which can be calculated as 0.25(2622) - 0.20(2622), or 0.25(2622) - 0.20(2622).
She consequently saved $131.10
