1) Problem: A recipe for chocolate chip cookies requires 2 cups of flour. If you want to make 4 batches of cookies, how many cups of flour do you need in total?
Solution: To find the total amount of flour needed, we need to multiply the amount of flour required for one batch by the number of batches. 2 cups of flour x 4 batches = 8 cups of flour.
Answer: You need 8 cups of flour in total.
2) Problem: A store is having a sale where all items are 20% off. If a shirt originally costs $25, what is the sale price?
Solution: To find the sale price, we need to multiply the original price by the discount percentage and subtract it from the original price. $25 - (20% of $25) = $25 - ($25 * 0.20) = $25 - $5 = $20.
Answer: The sale price of the shirt is $20.
3) Problem: A rectangular garden has a length of 12 meters and a width of 8 meters. What is the area of the garden?
Solution: To find the area of a rectangle, we need to multiply the length by the width. 12 meters x 8 meters = 96 square meters.
Answer: The area of the garden is 96 square meters.
4) Problem: Evaluate the expression: 3 + 4 x (5 - 2).
Solution: According to the order of operations (PEMDAS/BODMAS), we need to perform the operations inside the parentheses first. 5 - 2 = 3. Then, we multiply 4 by 3 and add 3 to the result. 4 x 3 + 3 = 12 + 3 = 15.
Answer: The expression evaluates to 15.
5) Problem: A car travels at a speed of 60 miles per hour. How far will it travel in 3 hours?
Solution: To find the distance traveled, we need to multiply the speed by the time. 60 miles per hour x 3 hours = 180 miles.
Answer: The car will travel 180 miles in 3 hours.
6) Problem: A pizza is divided into 8 equal slices. If 3 friends each eat 2 slices, how many slices are left?
Solution: To find the number of slices left, we need to subtract the number of slices eaten from the total number of slices. 8 slices - (3 friends x 2 slices) = 8 slices - 6 slices = 2 slices.
Answer: There are 2 slices left.
7) Problem: Simplify the expression: 12 ÷ (4 + 2) - 3.
Solution: According to the order of operations, we need to perform the addition inside the parentheses first. 4 + 2 = 6. Then, we divide 12 by 6 and subtract 3 from the result. 12 ÷ 6 - 3 = 2 - 3 = -1.
Answer: The expression simplifies to -1.
8) Problem: A store sells apples for $0.50 each and oranges for $0.75 each. If John buys 4 apples and 3 oranges, how much does he spend in total?
Solution: To find the total amount spent, we need to multiply the price of each item by the quantity and then add the results. (4 apples x $0.50) + (3 oranges x $0.75) = $2 + $2.25 = $4.25.
Answer: John spends $4.25 in total.
