Note: Exercises preceded by an asterisk are of a more challenging nature.In preparing a certain recipe, a chef uses 5 oz of ingredient A, 4 oz of ingredient B, and 6 oz of ingredient C. If 90 oz of this dish are needed, how many ounces of each ingredient should be used?

To determine

To find:

The number of ounces of each ingredient to be used.

Explanation

Given:

In preparing a certain recipe, a chef uses 5 oz of ingredient A, 4 oz of ingredient B, and 6 oz of ingredient C. In total 90 oz of this dish is needed.

Calculation:

Let us assume that x oz of ingredient A, y oz of ingredient B and z oz of ingredient C are needed to make the dish.

The chef uses 5 oz of ingredient A, 4 oz of ingredient B, and 6 oz of ingredient C.

x:y:z=5:4:6

Let x=5m,y=4m,z=6m

Since 90 oz of the dish is needed, 5m+4m+6m=90.

Now let us find the value of m.

5m+4m+6m=9015m=90m=9015m=6

We have x=5m
