Andri hand-made graduation invitations to send to her friends and family. the materials for each invitation cost $3. if andri made 112 invitations, how much did she spend on invitation materials in all?

336$

Step-by-step explanation:

Given: Each invitation costs a total of 3$.

Given: There were a total of 112 invitations made.

So, the question is asking you to find the total amount spent making the invitations. To do so we need to find the product/sum. Product in mathematical terms is used to describe the answer to a multiplication problem. Sum on the other hand is used to describe the answer to an addition problem. Now you could just add, but multiplication is a better way of simplifying the problem. So instead of saying 3 + 3 + 3 + 3.. or 112 + 112 + 122, we say 122 x 3 = x.

Now that we've created the equation, we can find the answer.

122 x 3 = 336

Andri spent 336$ on materials for her invitations.

Good luck! c:

40% off the regular price is the correct answer.
