The directions on a sewing pattern say to cut an extra 15% of fabric to account for error. Chloe needs 0.75 yardof fabric to mak
Vlada [557]

Answer: D. Chloe did not cut enough fabric because she only cut the amount of extra fabric.

Step-by-step explanation:

From the question, we are informed that a direction on a sewing pattern say to cut an extra 15% of fabric to account for error and that Chloe needs 0.75 yard of fabric to make a skirt.

Based on the information given in the question, the extra fabric will be:

= 15% × 0.75

= 15/100 × 0.75

= 0.15 × 0.75

= 0.1125

Therefore, the correct amount of fabric to cut will then be the amount of yard needed for the skirt plus the extra. This will be:

= 0.75 + 0.1125

= 0.8625 yards

Based on the above calculation, Chloe did not cut the correct amount of fabric as she only cut the amount of extra fabric.

I've already saved $68 for the $200 video game system. How many hours does raj need to work to earn the remainder of the money h
gladu [14]

Total amount needed for the video game = $200

Total amount of money saved = $68

Amount of money that is needed to be saved = 200-68  =132

So raj needs to work additional hours in order to earn the remaineder$132 for the video game

Hourly wage = $5.5

So, number of hours that Raj needs to work to earn $132 = $132/5.5 = 24 hours

Number of hours that Raj needs to work to earn the remainder of the money  = 24 hours
