A couple is required by their lender to have a down payment of 20% of the purchase price of the home they want to buy. If the co
Stella [2.4K]

Down payment is 20% of the price of the home. Since the couple saved $35,000, and assuming they will pay the whole money as down payment, the highest priced home they can get is a price whose 20% is $35,000.

We can setup an equation in x (being the price of home) to get the price of the most expensive home they can buy.

<em>Which number (x) , multiplied by 20%, is equal to $35,000?</em>

<em>x(0.2)=35,000\\x=\frac{35,000}{0.2} \\x=175,000</em>

So, the most expensive house they can buy is worth $175,000.

The answer is 4 cm because the formula for a cone is V=π r^2 h/3, and the formula for a cylinder is V=π r^2 h, and the cone's volume is V≈301.59, and, a cylinder with

r=4 and h=6 is V≈301.59

Therefore the answer is
