Question

Let SSS represent the number of sunflower plants and LLL represent the number of lily plants Ezra's water supply can water.

0.7S+0.5L \leq 110.7S+0.5L≤110, point, 7, S, plus, 0, point, 5, L, is less than or equal to, 11
Ezra waters 101010 lily plants. How many sunflower plants can he water at most with the remaining amount of water?

Answer 1

Ezra can water at most approximately 8 sunflower plants with the remaining amount of water.

Explanation:

Given the inequality function

0.7S+0.5L≤11 where S represent the number of sunflower plants and L represent the number of lily plants Ezra's water supply can water, if Ezra waters 10 lily plants, then we can calculate the maximum amount of sunflower plant that he can water with the remaining amount of water by simply substituting L = 10 into the inequality function as shown;

0.7S+0.5L≤11

0.7S+0.5(10)≤11

0.7S+5≤11

Taking 5 to the other side:

0.7S≤11-5

0.7S≤6

S≤6/0.7

S≤8.57

This shows that Ezra can water at most approximately 8 sunflower plants with the remaining amount of water.
