To work out the profit, firstly, you have to work out the cost of buying them, which is $15 multiplied by 100, which is $1500. You then have to work out what he sold them all at, which is $29.99 multiplied by 100, which is $2999. You then have to subtract $1500 from $2999, giving you $1499. Therefore, Ace made $1499 in profit.
Hope this helps :)

Answer:
64 ft²
Step-by-step explanation:
10 ft · 10 ft
100 ft²

6 · 6 = 36
36 ÷ 2 = 18
18 ft² + 18 ft² = 36 ft²
100 ft² - 36 ft²
64 ft²
From least to greatest it would be: 1.2, 1.23, 2.31, 3.2 I believe hope that helped
Do 2x60 which you'll get 120! Multiply 120 by 60, and it should be 7200 megabytes per hour!
