Question

Andre is in charge of cooking brócoli and zucchini for a large group he had to spend all 17$ he has and Cary 10 pounds of veggies zucchini cost $1.50 per pound and broccoli cost $2 per pound o

Answer 1

This is an example of equation with two unknowns. Andre bought x pounds of zucchini and y pounds of broccoli and we also know that there was 10 pounds of veggies in total. So, we can write:

$1.5 • x + $2 • y = $17

x + y = 10

From the second equation we can say that:

y = 10 - x

We can now enter this value of y into the first equation:

1.5 • x + 2 • (10-x) = 17

1.5 • x + 20 - 2 • x = 17

1.5x - 2x = 17 - 20

-0.5x = -3

0.5x = 3

x = 6

If x=6, then y=10-6, which is 4.

That means that Andre bought 6 pounds of zucchini and 4 pounds of broccoli.
