NEED HELP FAST!!! Find the percent of increase from 260 to 430. Round to the nearest tenth of a percent if necessary.

1 answer:

5 0

You started out with 260, and increased to 430.
The amount you increased was (430 - 260) = 170

170 is (170/260) = 65.4% of what you started with.

============================

Another way:

The new amount is (430/260) of the old amount.

430 / 260 = 1.654 = 165.4%

The original amount was 260.
You started with 100% of it.
You ended up with 165.4% of it.
That's an increase of 65.4% .

MAXImum [283]

Answer:

$108\ minutes$

Step-by-step explanation:

1) we know that

Sally can paint the wall in 54 minutes

The 100% of the wall ------> she can paint in 54 minutes

by proportion

calculate how much is the percent of the work in 36 minutes

$\frac{100\%}{54} =\frac{x\%}{36}\\ \\x=36*100/54\\ \\x=66.67\%$

That means

Sally in 36 minutes can paint the 66.67% of the wall

2) Sally and Ethan work together, they can paint the wall in 36 minutes

Ethan in 36 minutes can paint (100%-66.67%)=33.33%

by proportion

Calculate how much time does it take for Ethan to paint the wall by herself

$\frac{33.33\%}{36} =\frac{100\%}{x}\\ \\x=36*100/33.33\\ \\x=108\ minutes$
