The SHS step team is selling shs spirit t-shirts to raise money. The orange/black shirt sells for $15 and the black/white shirt
IRINA_888 [86]

Answer:

Option A)

15x + 10y \geq 1000

Step-by-step explanation:

We are given the following in the question:

Cost of orange/black shirt = $15

Cost of black/white shirt = $10

Amount of money to be raised is atleast $1000.

Let x be the amount of orange/black shirt and y be the amount of  black/white shirt.

Thus, we can write the inequality:

15x + 10y \geq 1000

That is the total cost of orange/black shirt and black/white shirt should be greater than or equal to $1000.

Thus, the correct answer is

Option A)

15x + 10y \geq 1000
