Hugh has to earn at least $400 to meet his fundraising goal. he has only 100 books that he plans to sell at $8 each. which inequality shows the number of books, x, hugh can sell to meet his goal? (1 point)  40 ≤ x ≥ 100   50 ≤ x ≥ 100   50 ≤ x ≥ 400   20 ≤ x ≥ 400

50 ≤ x ≤ 100

Step-by-step explanation:

The variable x represents the number of books Hugh needs to sell to earn at least $400. The 400 needs to be replaced with 100 because that is the highest number of books Hugh has to sell.

168

step-by-step explanation:

first off, we know that he drove 3.5 hours at a rate of 48 mph.

knowing that, we want to see how many miles he drove all-together.

in this case, we can just multiply 48 by 3.5.

48 * 3.5 = 168
