Answer:
333.67 miles
Step-by-step explanation:
She drives her car 91 mi on 3 gal of gas
That’s 91 mi = 3 gal
How many miles can she drive on 11 gal of gas .
Let the mile she can drive by 11 gal of gas be A
At the same rate ,
91 mi = 3 gall
A mi = 11 gal
Cross multiply
A x 3 = 91 x 11
A x 3 = 1001
Divide both sides by 3
A x 3/3 = 1001/3
A = 333.67 miles
At the same rate she’ll drive 333.67 miles on 11 gal of gas
Given:
Current population = x
The population of a city is expected to decrease by 6% next year.
To find:
The expression that represents the expected population next year.
Solution:
We have,
Current population = x
Decrease rate = 6%.
Expected population next year = Current population - 6% of Current population
=
=
=
Therefore, the expression for the expected population next year is 0.94x.
