Question

Laura has to buy stickers, erasers, and a pencil. She can only spend $5. A sticker costs $0.35, an eraser costs $0.99, and a pencil costs $0.59. Can Laura buy 3 stickers and 3 erasers?

[Use the inequality 0.35x + 0.99y + 0.59 ≤ 5]
Yes, because the total will be $3.62

Yes, because the total will be $4.61

No, because the total will be $5.62

No, because the total will be $5.93

Answer 1

$5-(3x.35)-(3x.99)-.59=.39
yes with .39 left so they spent 4.61

Answer 2

The correct option is B) Yes, because the total will be $4.61

Explanation:

Consider the provided inequality.

0.35x + 0.99y + 0.59 ≤ 5

Where x represents the number of sticker and y represents the number of eraser.

Laura want to buy 3 stickers and 3 erasers.

Substitute the value of x = 3 and value of y = 3 in the above inequality and identify whether the inequity holds.

0.35(3) + 0.99(3) + 0.59 ≤ 5

1.05 + 2.97 + 0.59 ≤ 5

4.61 ≤ 5

4.61 is less than 5. Thus, the inequality holds.

Hence, the correct option is B) Yes, because the total will be $4.61
