Question

Seven pieces of cardstock sell for $3. Tanesha spends $57 on cardstock. How many pieces of cardstock does Tanesha buy?

Answer 1

Hey there! :)

Answer:

133 pieces.

Explanation:

If 7 pieces of cardstock sell for $3, we can set up a proportion to determine the amount of pieces bought in pieces/ money spent:

`(7)/(3) = (x)/(57)`

Cross multiply:

7 · 57 = 3 · x

399 = 3x

Divide both sides by 3:

x = 133 pieces. This is the amount of pieces bought.
