Linda has to buy stickers, erasers, and a pencil. She can only spend $3. A sticker costs $0.35, an eraser costs $0.99, and a pencil costs $0.59. Can Linda buy 3 stickers and 2 erasers?

[Use the inequality 0.35x + 0.99y + 0.59 ≤ 3]

Yes, because the total will be $1.62
Yes, because the total will be $2.93
No, because the total will be $3.62
No, because the total will be $5.93

Answer:

No, because the total will be 3.03 + 0.59 = £3.62

Explanation:

0.35 x 3 = 1.05

0.99 x 2 = 1.98

1.05 + 1.98 = 3.03 = $3.03 without pencil (0.59)

= 1.05 + 1.98 = 3.03 ≤ 3 is incorrect as 3.03 should be the maximum equal to or appear the other way round.

Inequality for all 6 items using the same inequality shown 0.35x+0.99y+0.59< 3 is incorrect No, because the total will be 3.03 + 0.59 = £3.62

and inequality of higher amounts than $3 should be shown other way round where ≤ 3 means it stops at $3 and is less or equal.

and inequality facing towards means it would be equal but more than $3
