Tim decides to get animals for his zoo. He buys 3 goats for $400 each. He gets twice as many llamas which cost 50% more each. How much did he spend?
Let's think: The goats cost 3 * 400 = $1200. He buys 3 * 2 = 6 llamas. Each llama cost 400 * 1.5 = $600. So he spends 600 * 6 = $3600 on llamas. So the total cost was 1200 + 3600 = $4800.. The answer is: 4800.

Melony makes $21 of profit every time she sells 3 shirts and four times as much profit when she sells two pairs of sandals. How much profit will she make if she sells 7 shirts and 3 pairs of sandals?
Let's think: Melony makes $21 * 4 = $84 of profit for two pairs of sandals. Melony makes $84 / 2 pairs = $42 of profit per pair of shoes. Melony makes $21 / 3 shirts = $7 of profit per shirt. For seven shirts, Melony will make 7 shirts * $7 = $49 of profit. For three pairs of sandals, Melony will make 3 pairs * $42 / pair = $126 of profit. Melony will make a total of $49 + $126 = $175 of profit.. The answer is: 175.

Peter is raking leaves. It takes him 15 minutes to rake 3 bags of leaves. If he keeps raking at the same rate, how long will it take him to rake 8 bags?
Let's think: We are trying to figure out how long it will take Peter to rake 8 bags of leaves, so we'll call that Y. And we know Peter can rake 3 bags of leaves / 15 minutes = 8 bags of leaves / Y. Next, we will multiply to find the cross - products. 3 x Y = 15 x 8 or 3Y = 120. We want to get figure out Y, so we need to get it by itself by dividing by 3, like this: 3Y / 3 = 120 / 3 or Y = 40 minutes.. The answer is: 40.

John buys 3 reels of 100m fishing line. He cuts it into 10m sections. How many sections does he get?
Let's think:
He buys 3 * 100 = 300m. So he gets 300 / 10 = 30 sections.. The answer is: 30.
