Question

Patrick wants to buy some songs and videos from an online media

store.
Songs (s) cost $1 each.
Videos (v) cost $2.50 each.
Patrick wants to spend at least $25 at the store.
Which inequality represents the number of songs and videos Patrick
could buy if he wants to spend at least $25 at the store?
.
.
.
A. s+2.5v≥25
B. s+2.5v ≤25
C. 2.5s+v≤25
D. 2.5s+v≥25

Answer 1

A

This because you know that the video are 2.50 so the v variable has to be next to the 2.50. Patrick wants to spend 25 at least meaning he woukd spend more.

Answer 2

s + 2.5v ≥ 25

Explanation:

Framing inequalities:

Cost of 1 song = $1

Cost of 's' songs = s * 1 = s

Cost of 1 video = $2.50

Cost of 'v' videos = 2.50 * v = 2.5v

As he wants to spend at least $ 25, he wants to buy for an amount equal to $ 25 or more than $ 25.

Total amount to spend ≥ $ 25

s + 2.5v ≥ 25
