Question

Sheri is saving up for college textbooks. She has saved $840, but she needs at least $2,460 to cover the cost of the textbooks.

Sheri has decided to tutor students for $27 per session to add to her savings.
Which inequality represents, x, the number of sessions Sheri needs to tutor?
A. X 60
B. X2 92
C. X291
D. x2 122

Answer 1

A. x ≥ 60

Explanation:

Amount already saved + amount tutoring = at least $2,460

⇒ 840 + 27x ≥ 2,460

⇒ 27x ≥ 1620

⇒ x ≥ 60

Therefore, Sheri has to give at least 60 tutoring sessions.
