Correct question
A chef locates a pre-made tuna salad that is nearly identical to the one she makes from scratch in her sandwich shop. To make it from scratch, an $8.25/hour employee needs 20 minutes to prepare the tuna salad. The ingredients cost $12.18 and yield 10 four-ounce servings. The chef can purchase the pre-made tuna salad at $26.99 for a 5 pound tub. Calculate the cost per portion for the scratch-made and the premade versions. If cost were the only factor, should the chef make or buy this product?
Answer:
If cost were the only factor, the chef should not make version of the tuna salad from scratch because it is expensive that the premade version
Step-by-step explanation:
For tuna: Made from scratch
The ingredients cost $12.18 and yield 10 four-ounce servings.
10 servings = $12.18
1 serving = x
10 × x = 1 × $12.18
x = $12.18/10
x = $1.218
Hence, 1 four ounce serving cost $1.218
The chef can purchase the pre-made tuna salad at $26.99 for a 5# tub.
5 pound tub salad = $26.99
1 pound tub of tuna salad = x
5 × x = 1 × $26.99
x = $26.99/5
x = $5.398 per pound
Converting to ounces
0.0625 pound = 1 ounce
5 pound = x
x = 5/0.0625
x = 80 ounces
80 ounces of tuna salad = $5.398
4 ounces of tuna salad = x
80 × x = 4 × $5.398
x = 4 x 5.398/80
x = $0.2699
Hence, 1 4 ounce pre made tuna salad cost = $0.2699
Hence, the cost per portion for the scratch-made is $1.218 per 4 ounces servings and the premade versions is $0.2698 per 4 ounce servings
If cost were the only factor, the chef should not make version of the tuna salad from scratch because it is expensive that the premade version
