At a coffee shop, 7 customers order coffee at $5 each and 8 customers order tea at $4 each. How much money did the coffee shop make?
Let's think: Sale from coffee is 7 x $5 = $35. Sale from tea is 8 x $4 = $32. Total sales is $35 + $32 = $67.. The answer is: 67.

Paul uses 1 can of frosting to frost a layer cake. He uses a half can of frosting for a single cake, or a single pan of brownies, or a dozen cupcakes. For Saturday, he needs to have 3 layer cakes, 6 dozen cupcakes, 12 single cakes and 18 pans of brownies ready and frosted for customer pick up. How many cans of frosting will he need?
Let's think: He needs 1 can of frosting per layer cake and he needs to make 3 layer cakes so that's 1 * 3 = 3 cans of frosting. There are 6 dozen cupcakes,12 single cakes and 18 pans of brownies for a total of 6 + 12 + 18 = 36 orders. Each of the 36 orders needs 1 / 2 can of frosting so they need 36 * .5 = 18 cans of frosting. He needs 3 cans of frosting for the layer cakes and 18 cans for the remaining items for a total of 3 + 18 = 21 cans of frosting.. The answer is: 21.

A rectangle has a length of 40 meters and a width of 20 meters. A similar smaller rectangle has half the length and width of the big rectangle. What's the area of the smaller rectangle?
Let's think: The length of the smaller rectangle is 1 / 2 * 40 = 20 meters. The width of the smaller rectangle is 1 / 2 * 20 = 10 meters. Since the area of a rectangle is found by multiplying the length times the width, the total area of the smaller rectangle is 20 * 10 = 200 meters square.. The answer is: 200.

Out of the 200 cookies that Javier baked from the recipe he learned online, his wife took 30%, and his daughter took 40 from the remaining cookies. If he ate half of the remaining cookies, how many cookies did they not eat?
Let's think:
From the 200 cookies, Javier's wife ate 30 / 100 * 200 = 60. After the wife ate 60 cookies, the number of cookies that remained was 200 - 60 = 140. The daughter also ate 40 cookies leaving 140 - 40 = 100 cookies. If Javier ate half of the remaining cookies, he ate 1 / 2 * 100 = 50. The number of cookies that remained is 100 - 50 = 50.. The answer is: 50.
