BRAINLIEST! URGENT! Can someone please help me with this? I know its C cause someone answered it. ut didnt explain.

c) 160,000

Step-by-step explanation:

Since we know that the population of both city x and city y are equal in 2015, we can use the population growth of population of city x to find the population in 2015:

120,000 x 1.2 = 144,000.

Now, since we know that City Y's population decreased 10% from 2010 to 2015, we can divide the 2015 population of city Y (which is the same as city x - 144,00) by 1 - decrease rate to find city y's population in 2010:

1 - .1 = .9

144,000 / .9 = 160,000

I hope this helps!

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
