irinina [24]

Answer:

60%

Step-by-step explanation:

If I get you right, you're asking for the percentage gain to the nearest percentage, right?

Now to do this, we need to get the amount of profit she made. That's quite easy, we only need to subtract the cost price from the selling price. And that equals $15 - $9.38 that equals $5.62.

Now, we divide this value by the cost price and multiply by 100% to get the percentage gain.

I.e 5.62/9.38 × 100%.

That gives 59.9% , which equals 60% when approximated to the nearest percentage.

Zoe used 3/8 of her ribbon to wrap a present. If she uses 9 feet of ribbon for the present how much ribbon did Zoe have it first
MArishka [77]

Let the total ribbon Zoe had was x feet.

Out of x feet, she used 3/8 part of it.

Hence, \frac{3x}{8}

3/8 part of the original ribbon is equal to 9 feet.

Hence, we get

\frac{3x}{8} = 9

=> Multiply 8 on both sides.

3x=72

Divide both sides by 3

\frac{3x}{3}=\frac{72}{3}

x=24 ft

Zoe had 24 feet of ribbon in starting... Answer
