Question

Andy is modifying a muffin recipe and decides to increase the amount of cocoa powder by 7 tablespoons

and then he triples the entire recipe. If c is the number of tablespoons of cocoa powder in the original
recipe, which expression represents the amount of cocoa powder Marcus needs?
A) 3c+7

B) 3(c+7)

C) 3c+21

D) c+21

Answer 1

Andy increases the original amount of cocoa powder in the recipe, represented as 'c', by 7 tablespoons and then triples the entire recipe. The correct expression for the total amount of cocoa needed is 3(c + 7).

Step-by-step explanation:

To solve Andy's cocoa powder problem, we need to apply basic algebraic manipulation. The original amount of cocoa powder is represented by c. Andy increases the amount of cocoa by 7 tablespoons, so the modified amount is c + 7 tablespoons. Since he then triples the entire recipe, we need to multiply this modified amount by 3 to get the total amount of cocoa powder needed. The correct expression is therefore 3(c + 7).
