Beth is paid $225 per week plus a commission of $20 per sale. This week she wants to earn at least $650. If s represents the min
imum number of sales that Sara needs this week, which inequality represents all the possible values of s? A) 20s + 225 ≥ 650
B) 20s + 225 ≤ 650
C) 225s + 20 ≥ 650
D) 225s + 20 ≤ 650
Earning a commission of $20 per sale, where s represents the number of sales, gives us the expression 20s. Adding to this the weekly salary of $225 gives us 20s+225.
Since Sara wants to earn at least $650, she can earn this much or more. This gives us the inequality symbol "greater than or equal to," which gives us the inequality
