Answer:
Jessica lived 10 months in Spain and 8 months in Colombia.
Step-by-step explanation:
Let x be the months Jessica spent in Spain, and y the months she spent in Colombia:
1. x + y = 18
Using the information of words per month learned in each country, we can also write the equation:
2. 160 * x + 200 * y = 3200
So now we have a system of <u>two equations and two unknowns</u>.
First we <u>express y in terms of x, in the first equation</u>:
We <u>replace y in the second equation</u>:
- 160 * x + 200 * (18 - x) = 3200
And <u>solve for x</u>:
- 160x + 3600 - 200x = 3200
Finally we <u>use that value of x in the first equation and solve for y</u>:
Jessica lived 10 months in Spain and 8 months in Colombia.
There are 550 students at the green country middle school and 220 of them ride the bus to school. What percent of the students ride the bus?
The fraction 
represents the number of students that ride the bus to school out of all the students.
To find what percent of students ride the bus to school, we can turn the fraction 
into a percent.
We can first reduce this fraction by dividing both the numerator and denominator by the Greatest Common Factor of 220 and 500 using 20.
220 ÷ 20 = 11
500 ÷ 20 = 25
11 ÷ 25 = 0.44
0.44 × 100 = 44%
Therefore, 44% of the students ride the bus to green country middle school.
