The heights of a maple tree and a cherry tree have a ratio of 5:2. If the maple tree grew 20 cm and 20 cm was cut off the top of
elena-14-01-66 [18.8K]
Let x be the <span>heights of a maple tree and y be the height of the cherry tree.
We know: 
</span>\frac{x}{y} = \frac{5}{2}
<span>The new ratio is obtained like this:
</span>\frac{x+20}{y-20} = \frac{3}{1}.
From the above equation we get x= (y-20)\frac{3}{1} -20.
then \frac{ (y-20)\frac{3}{1} -20}{y} = \frac{5}{2}
Solving the above equation for y we get: y=160
So x=400
So the first tree is (400-160=240) more taller than cherry tree.

A market buys watermelons for $1.25 they want to make a 20% profit what should they charge for the watermelons
Serhud [2]

Answer: $1.50

Step-by-step explanation:

Cost price of watermelon = $1.25

Profit percent = 20%

Profit = Profit percent × Cost price

= 20% × $1.25

= 20/100 × $1.25

= 0.2 × $1.25

= $0.25

Selling price = Cost price + Profit

Selling price = $1.25 + $0.25

Selling price = $1.50

They should charge $1.50 for the watermelons
