The number of pieces of sausage needed by a pizza restaurant is given by the equation [tex] s = 21n [/tex]. In this equation, [tex] n [/tex] is the number of pizzas the restaurant will make. How many pieces of sausage are needed to make 55 pizzas?

A. 1155
B. 76
C. 855
D. 34



Answer :

To find out how many pieces of sausage are needed to make 55 pizzas, you can use the given equation [tex]\( s = 21n \)[/tex]. Here, [tex]\( s \)[/tex] represents the total number of pieces of sausage, and [tex]\( n \)[/tex] represents the number of pizzas.

Given:
[tex]\[ n = 55 \][/tex]
[tex]\[ s = 21n \][/tex]

Step-by-Step Solution:

1. Substitute the value of [tex]\( n \)[/tex] into the equation [tex]\( s = 21n \)[/tex].
[tex]\[ s = 21 \times 55 \][/tex]

2. Multiply 21 by 55 to find the value of [tex]\( s \)[/tex].

After calculating, you find that:
[tex]\[ s = 1155 \][/tex]

Therefore, the number of pieces of sausage needed to make 55 pizzas is 1155.

The correct answer is:
A. 1155
