[I have no idea how to do this]

jekas [21]

Answer:

We have 16 ounces of 3% H2O2

How many ounces of 30% H2O2 do we add to make a 10% H2O2 solution?

let x = amount of ounces of 30% H2O2 to add

.03 * 16 + .30x = .10 * (16 + x)

.48 + .30x = 1.6 + .1x

.2x = 1.12

x = 5.6 ounces

11. The price of a bottle of water at a store decreases from $1.65 to $1.40. Rounded to the nearest

ELEN [110]

Answer:

A. 15.2%

Step-by-step explanation:

Subtract the new price from the old one to find the dollar amount that the water bottle price was reduced.

$1.65-1.40=0.25$

The price was reduced by 25 cents, but we need to find the percentage. To do that, we divide the price reduction by the original price.

$0.25/1.65=0.152$

And then move the decimal place over two spots (multiply by 100)
