Question

Part C. Cindy also wants to buy some plants for her garden. She has at most $30 to spend on the plants. She buys 6 tomato plants for $12, and she wants to spend the rest of her money on herb plants. Each herb plant costs $2.75. Write an inequality for the number of herb plants Cindy can buy. Let h represent the cost of each herb plant.

Solve your inequality to find the greatest number of herb plants Cindy can buy with the money she has to spend.

Answer 2

12 + 2.75h ≠ 30

Or

31.26 ≠ 30

Explanation:

12 + 2.75h = 30

We want to single out the variable so subtract 12 from both sides.

12 + 2.75h = 30

-12 -12

Now we can move down the number and then divide.

12 + 2.75h = 30

-12 -12

2.75h = 18

h ≠ 6.54545454(A repeating number.)

Since this is a repeating number we’ll take the whole number and multiply it by 2.75. Then we’ll add the 12 and compare.

2.75 x 6 = 16.5 + 12 = 28.5 < 30

28.5 is less than 30 so this is true correct answer. See what happens when you add another 2.75.

28.5 + 2.75 = 31.25 > 30

The question says *at most* meaning it’s can be equal to or less than 30. 31.25 is great than 30 so it cannot be this number.

There’s your answer.

Either 12 + 2.75 ≠ 30 or 31.25 ≠ 30
