Textbook Problem

Use ratio and proportion to solve the following business situations.

Eighty ounces of Lazy Lawn fertilizer covers 1,250 square feet of lawn, a. How many ounces would be required to cover a 4,000-square-foot lawn?

b. If Lazy Lawn costs $1.19 for a 32-ounce bag, what is the total cost to fertilize the lawn?

**(a)**

To determine

**To calculate:** The number of ounces, that can cover the lawn of area

Explanation

**Given Information:**

The lawn of area

**Formula used:**

To solve the proportional problem by using cross multiplication, follow the steps as mentioned below.

Step

Step2: Set the proportion in the ratio of

Step3: Multiply numerator of the left side ratio with the denominatior of right side ratio and place the product on one side of the equal sign.

Step4: Multiply denominatior of the left side ratio with the nominatior of right side ratio and place the product on other side of the equal sign.(step2 and step3 performing togeter is consider as cross multiplication)

Step5: Solve the unknown value.

**Calculation:**

Suppose that *X* be the number of ounces that can cover the lawn of area

Consider the area

Apply cross multiplication, this gives,

This equation represents that

**(b)**

To determine

**To calculate:** The cost of ounces required to cover the lawn of area
