Sarah uses balsa wood to build airplane models. After completing a model, she had a strip of balsa wood measuring 7/8 of a yard left over. Shawn the Weirdo wants to buy half of the strip from Sarah. If Sarah paid $2.00 for each yard, how much should she charge Shawn for the strip he buys?

Thank you...

You're welcome.

To find out how much Sarah should charge Shawn for the strip he wants to buy, we need to calculate the length of the strip and then determine the cost based on the price per yard.

First, we know that Sarah has a strip of balsa wood measuring 7/8 of a yard left over. To determine the length of the strip in yards, we divide the numerator (7) by the denominator (8):

Length of the strip = 7/8 yards

Next, since Shawn wants to buy half of the strip, we need to find half of 7/8 of a yard:

Length of the strip Shawn wants to buy = (1/2) * (7/8) = 7/16 yards

Now that we know the length of the strip Shawn wants to buy, we can calculate the cost. Sarah paid $2.00 for each yard of balsa wood, so we need to find the cost of 7/16 of a yard:

Cost = (7/16) * $2.00

To simplify this calculation, we can multiply the numerator (7) by the price ($2.00) and then divide by the denominator (16):

Cost = (7 * $2.00) / 16
= $14.00 / 16
= $0.875

Therefore, Sarah should charge Shawn $0.875 for the strip of balsa wood he wants to buy.

(1/2) * (7/8) = 7/16

(7/16) * $2.00 = 14/16 = 7/8 = $0.875 = $0.88
