X= r-h/y
h= xy-r/-1
r= xy+h
In this question, we're assuming Ralph had 0 in his saving funds to start with.
The glasses cost 1200 dollars.
There are 12 months in a year.
Each month, Ralph is given his check two times, that means that Ralph receives his check 2(12), or 24, times per year.
Divide 1200 (the cost of the glasses) by 24 (the amount of times Ralph is given his check)
1200 / 24
Divide both numerator and denominator by 12
100 / 2
Simplify
50
Ralph should have put 50 dollars per pay check to pay for the glasses.
A is your answer.
Have an awesome day! :)

Step-by-step explanation:
The return trip took 1 hour 42 minutes longer
Further explanation:
The distance will remain same on return.
The formula for speed is given by:

Let d be the distance
s1 be the speed while going and s2 be the speed while returning
and
t1 be the time while going and t2 be the time while returning
d=500 miles
s1=60 miles per hour
s2=50 miles per hour
We have to calculate time for both trips,
So,
<u>Time while Going:</u>
<u>
</u>
<u>Putting the values of d and s1</u>
<u>
</u>
<u>Converting 8.3</u>
8 will be the hours,
for 0.3 hour
0.3*60=18 minutes
The first trip took 8 hours and 18 minutes.
<u>Time while returning:</u>

Putting the values of d and s1

The difference of both times is: 1 hour 42 minutes
So,
The return trip took 1 hour 42 minutes longer
