Jamal spends $63.50 on supplies to make some woodworking items. If he sells his items for $7.25 each, how many items does he have to sell to make back his investment and make $50 profit?

15.65 so round it to 16

Step-by-step explanation:

Add 50 and 63.5 then divide by 7.25

16 items

Step-by-step explanation:

He spent $63.50 so he has to earn that back by selling items and also make a $50 profit. So you add $63.50+$50 which is 113.50 and then divide that by $7.25 because that is how much each item he sells costs. Once you do that you get 15.6551 but you can’t sell 15.6551 items so you round up to a whole number which gives you the answer that he has to sell 16 items.

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
