The sum of two numbers is 77. The greater number is 5 more than the smaller number. Which equation can be used to solve for the smaller number?

x(x − 5) = 77
x(x + 5) = 77
x − (x + 5) = 77
x + (x + 5) = 77

Chad wants to buy some books over the Internet. Each book costs $10.01 and has a shipping cost of $9.96 per order. If Chad wants to spend no more than $50 for his books, which inequality shows the maximum number of books, p, that he can buy?

9.96p − 10.01p ≤ 50, so p ≤ 1
9.96p + 10.01p ≤ 50, so p ≤ 2
9.96 − 10.01p ≤ 50, so p ≤ 3
9.96 + 10.01p ≤ 50, so p ≤ 4

(03.05 MC)

Sophia works in a clothing store and earns $40 per day. She earns an extra $5 for each outfit she sells. If Sophia wants to earn at least $70 per day, which inequality shows the minimum number of outfits, n, that she should sell?

40 + 5n ≤ 70, so n ≤ 6
40 + 5n ≥ 70, so n ≥ 25
40 + 5n ≤ 70, so n ≤ 25
40 + 5n ≥ 70, so n ≥ 6
