Answer 1

Hello!

The answer is:

The fabric will cost $4.58

D.$4.58

Why?

Since it's a conversion exercise, we need to pay special attention to the conversion procedure.

From the statement we know that:

$1ft=0.305m$

So, if she needs 10 feet of fabric, we need to convert it to meters, and then, calculate its cost.

We have that:

$10*1ft=10*0.305m\\\\10ft=3.05m$

Now, we have that each meter of fabric cost $1.50, so, 3.05m of fabric will cost:

$\frac{1m}{1.50(dollars)}=\frac{3.05m}{cost}\\\\cost=\frac{3.05m*1.50(dollars)}{1m}=4.575(dollars)=4.58(dollars)$

Hence, we have that the cost of the fabric will be $4.58.

The correct option is: D.$4.58​

Have a nice day!
