19. At a concession stand, popcorn costs $1.10 and nachos cost $2.35. One
day, the receipts for a total of 172 popcorn and nachos were $294.20.
How many popcorns were sold?

Sagot :

The number of popcorns sold is 88.

Two simultaneous equations

Two equations can be derived from the question:

a + b = 172 equation 1

1.10a + 2.35b = $294.20 equation 2

Where:

a = number of popcorns sold

b = number of nachos sold

How to determine the number of popcorns sold

In order to determine the number of popcorns sold, take the following steps:

Multiply equation 1 by 2.35

2.35a + 2.35b = 404.20 equation 3

Subtract equation 2 from 3

110 = 1.25a

Divide both sides by 1.25

a = 88
