1. Write an equation that represents how many total salads Raj needs to prepare (sss) when bbb guests choose a bowl of soup.


2. How many salads does Raj need to prepare if 21 guests choose a bowl of soup?

Answer 1

Answer:

1. s = 35 - 21

2. 14

Explanation:

Let t = total number of salads and bowls of soup.

Let s = number of salads.

Let b = number of bowls of soup.

1.

t = s + b

We are told the total number of people is 35, so we have t = 35.

35 = s + b

s + b = 35

Solve for s.

Answer: s = 35 - b

2.

b = 21

s = 35 - b

s = 35 - 21

s = 14

Answer: 14

2. 14

Explanation:

Let t = total number of salads and bowls of soup.

Let s = number of salads.

Let b = number of bowls of soup.

1.

t = s + b

We are told the total number of people is 35, so we have t = 35.

35 = s + b

s + b = 35

Solve for s.

Answer: s = 35 - b

2.

b = 21

s = 35 - b

s = 35 - 21

s = 14
