In a neighborhood, 2/5 of the houses are painted yellow. If there are 24 houses that are not painted yellow, how many yellow hou
grigory [225]

Answer:

There are 16 yellow houses in the neighborhood.

Step-by-step explanation:

We have that:

2/5 = 40% of the houses are painted yellow

1 - 2/5 = 3/5 = 60% of the houses are not painted yellow

If there are 24 houses that are not painted yellow, how many yellow houses are in the neighborhood?

The first step is finding the total number of houses in the neighborhood.

We have that 24 are not painted yellow, and this is 60%(0.6 decimal). How much is 100%?

We solve a rule of three

24 houses - 0.6

x houses - 1

0.6x = 24

x = \frac{24}{0.6}

x = 40

There are 40 houses. Of those, 40% are painted yellow.

0.4*40 = 16.

There are 16 yellow houses in the neighborhood.

I buy the same chips every week and my bill is normally $90.00. Why am I now being charged $108 for the exact same items? What p
Elden [556K]
Hi there! To find the percent of change, do change/original = x/100. The amount of change means to find the distance between two numbers and the original is the previous price. 108 - 90 = 18. Plug in the values in order to get 18/90 = x/100. Cross multiply the values in order to get 1,800 = 90x. Now, divide each side by 90 to isolate the variable. When you do, you get x = 20. The store increased their prices by 20%.
