Answer 2

Answer: $180

=======================================================

Step-by-step explanation:

• f = cost of a first class ticket
• c = cost of a coach ticket

Costs are in dollars

The first class ticket is 175% of the coach ticket, meaning

f = 1.75c

where the 1.75 is the multiplier pertaining to 175%

Think of it like saying 1 + 0.75 = 100% + 75% = 175%

In other words, the first class ticket is 100% of the coach ticket plus an extra 75% on top of that.

The difference in the two tickets is $135, allowing us to write

f - c = 135

------------

Let's plug in f = 1.75c and solve for c.

f - c = 135

1.75c - c = 135

0.75c = 135

c = 135/(0.75)

c = 180

The coach ticket is $180

---------------

We could stop here once we figure out the coach ticket cost.

If you want to, let's find the first class ticket cost

f = 1.75*c

f = 1.75*180

f = 315

Then notice how f - c = 315-180 = 135 to show the difference in prices is $135. The answer is confirmed.
