Question

The school band is ordering health bars to sell for a fundraiser. The company that sells the bars charges $0.40 per bar plus $20.00 for shipping regardless of the size of the order. The band must spend less than $200.00 on bars for the fundraiser. The inequality below relates x, the number of bars that could be ordered, with the shipping costs and their spending requirements.

0.40x + 20 < 200

Which best describes the number of bars the band can order?
They can order from 0 to 449 bars, but no more.They can order from 0 to 450 bars, but no more.Their order must contain 451 bars or more. Their order must contain 452 bars or more.

Answer 1

Hello!

You can solve this like a algebraic expression

0.40x + 20 < 200

Subtract 20 from both sides

0.40x < 180

Divide both sides by 0.40

x < 450

So the band can but no more than 449 heath bars

Hope this helps!

Answer 2

Answer: They can order from 0 to 449 bars, but no more.

Explanation:

Given: The school band is ordering health bars to sell for a fundraiser. The company that sells the bars charges $0.40 per bar plus $20.00 for shipping regardless of the size of the order. The band must spend less than $200.00 on bars for the fundraiser.

The inequality below relates x, the number of bars that could be ordered, with the shipping costs and their spending requirements.

`0.40x+20<200`

To solve for x, subtract 20 on both sides, we get

`0.40x<108`

Divide 0.40 on both sides, we get

`x<450`......... → the number of bars that could be ordered, with the shipping costs and their spending requirements must less than 450.

Thus, they can order from 0 to 449 bars, but no more.
