Question

Tasty Trunk Treats sends a selection of snacks in the mail each month. Andy bought a 3-month subscription for a friend. He used a one-time coupon and received 5 $ off the total cost. Andy paid 37 $ in all. Which equation can you use to find the regular cost, m, for each month?   Choices: (A)3(m - 5) = 37 (B)5m - 3 = 37 (C)3m - 5 = 37 (D)5(m - 3) = 37

Identify total cost and discount:  Identify the total cost Andy paid and the discount applied. Andy paid $37 after a $5 discount for a 3-month subscription. Set up equation for regular cost:  Set up the equation to find the regular monthly cost, m. The original total cost before the discount is $37 + $5 = $42 for 3 months. Write equation based on total cost:  Write the equation based on the total cost for 3 months. The equation is 3m = $42, where m is the cost per month. Solve for monthly cost:  Solve for m by dividing both sides of the equation by 3. m = $42 / 3 = $14 per month. Check equation with given choices:  Check if the equation fits any of the given choices. Rewriting the original scenario with the discount: 3(m - 5) = 37 fits because 3(14 - 5) = 3 * 9 = 27, which is incorrect. The correct setup should be 3m - 5 = 37, where the total cost minus the discount equals what Andy paid.
