Sagot :

The popcorn balls cost $1.00 each

Jumbo candy bars cost $1.50 each

This week they have made a total of $229 and have sold 79

popcorn balls.

First, let's make a function with includes this information.

Let's say that popcorn balls are x and Jumbo candy bars are y.

So the function would be

1.00x+ 1.50y = 229

We already have the x value which represents the total of popcorn balls sold this week, so replace this value in the function:

1.00x+ 1.50y = 229

1.00(79)+ 1.50y = 229

79.00 + 1.50y = 229

Solve the equation for y to find the total of candy bars sold.

79 + 1.50y = 229

1.50y = 229 - 79

1.50y = 150

y = 150/1.50

y = 100

So the have sold 100 candy bars this week
