Of the 240 sandwiches Joanna makes, 20% are tuna sandwiches, 40% are ham sandwiches, and the rest are egg salad sandwiches. How many egg salad sandwiches does Joanna make?

Respuesta :

20% as a decimal is 0.20. So, 240 x 0.20 is 48 tuna sandwiches, 40% as a decimal is 0.40 so 240 x 0.40 is 96 ham sandwiches. 48 + 96 is 144. So that means that the remaining 96 sandwiches are Egg Salad Sandwiches.

Answer:

The correct answer is 96.

Step-by-step explanation:

There are several ways to solve this exercise. Let's see one of them:

First let's analyze the information we have:

240 sandwiches represent 100%

20% are tuna sandwiches

40% are ham sandwiches

Therefore, the remaining 40% will be egg salad sandwiches.

So to solve this problem we only have to calculate 40% of 240, and we can do it by multiplying the percentage by the total, and dividing it by 100:

(40. 240): 100 =

9600: 100 = 96

The correct answer is 96 egg salad sandwiches.
