fenix001 [56]

Answer:

75

Step-by-step explanation:

Given :   In beanbags

             4 Cuts in upholstery

            15 are Understuffed  

             None 267

            Total 300

To Find : If the manufacturer makes 1500 beanbag chairs per day, how many of those chairs would they expect to be understuffed?

Solution :

We are given that out of total of 300 bags there are 15 understuffed

Let x be the no. of understuffed bean bags out of total of 1500.

⇒\frac{15}{300} =\frac{x}{1500}

⇒\frac{15*1500}{300} =x

⇒75=x

Thus  If the manufacturer makes 1500 beanbag chairs per day, 75 of those chairs would they expect to be understuffed .
