Emma had $230 - $60 = $170 left in her bank account after she withdrew $60. The next week, she deposited $60 x 2 = $120. Hence, she now has a total of $170 + $120 = $290 in her bank account.
The answer: 290

Let D be the cost of the dessert in dollars. The entree costs D + 5 dollars. D + (D + 5) = 23. 2D + 5 = 23. 2D = 18. D = 9. The entree costs $14.
The answer: 14

A gallon of milk makes $3 worth of butter because 2 x 1.5 = 3. A gallon of milk sells for the same amount as milk or butter because 3 = 3. She gets 48 gallons of milk because 4 x 12 = 48. She earns $144 selling the milk because 48 x $3 = 144.
The answer: 144
Reverse engineering the question: Brooke is milking cows and then selling the milk at the market for $3 a gallon. Whatever milk doesn't sell, she turns into butter. One gallon of milk equals 2 sticks of butter. She then sells the butter for $1.5 a stick. She has 12 cows. Each cow produces 4 gallons of milk. She has 6 customers, each of whom wants 6 gallons of milk. How much money does she earn if she sells all her milk and butter?

All together, Brenda and her friends make a group of 1 + 9 = 10 people. If they each want to eat 2 pizza slices, there should be 10 * 2 = 20 slices. Since a pizza has 4 slices, they will have to order 20 / 4 = 5 pizzas.
The answer: 5
