Question

Natalie works in a toy shop and earns $43 per day. She earns an extra $3 for each toy she sells. If Natalie wants to earn at least $70 per day, which inequality shows the minimum number of toys, n, that she should sell?

43 + 3n ≥ 70, so n ≥ 9
43 + 3n ≤ 70, so n ≤ 9
43 + 3n ≥ 70, so n ≥ 24
43 + 3n ≤ 70, so n ≤ 24

Answer 2

A?

Answer 3

yes

Answer 4

Just writing the paragraph into an inequality as you read it...

Earned = Initial Earnings + Earnings from toys

Answer 5

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

Answer 6

43 + 3*(#toys)

Answer 7

b?

Answer 8

Total Spent = Books + Shipping

Answer 9

Total = 10.01*(#books) + 9.96

Answer 10

and you want that less than or equal to the 50 total to spend

Answer 11

you don't want to multiply the shipping cost by the number of books, it is just a flate rate shipping per order of 9.96
