Question

On Saturday, the fruit and juice bar was selling 23 glasses of fruit punch an hour. By 4 p.m., they had sold 138 glasses. If their goal was to sell at least 276 glasses of fruit punch, which inequality can be used to find h, the number of hours they must stay open to make their goal?

Answer 1

What are your choices?

23h = 138

h = 6

276 - 138 = 138, so you would need an additional 6 hours at least.

Answer 2

I had the same question but it was that they were selling 30 an hour, and by 7pm they had sold 270 but their goal was to sell 360. Please help! Here were the possible answers:

a. 270 + 360 > 30h

b. 270 + 30h > 360

c. 270 + 30h < 360

d. 30h < 360 + 270
