Question

You have a rectangular plot measuring 16 ft by 35 ft in a community garden. You want to grow tomato plants that each need 8 square ft. Write and equation that models how many tomato plants and how many pepper plants you can grow. How many pepper plants can you grow if you grow 15 tomato plants?

Answer 1

16ft * 35ft = 560 ft²
t is the # of tomato plants
p is the # of pepper plants

560 = 8t + 8p

p = ? if t = 15:
560 = 8(15) + 8p
560 = 120 + 8p
8p = 440
p = 55
You can plant 55 pepper plants when there are 15 tomato plants in the garden.
Hope this helps! :)
