In these problems, it is always a good idea to find the total population. In this case, it would be the total number of people who went on the field trip.
28+18+4=50
There are 50 people total.
To find each fraction, just put the number of students/parents/teachers over 50 and simplify.
Students
28/50=14/25
Parents
18/50=9/25
Teachers
4/50=2/25

Answer:
I will do a step by step explanation to help you.
First, subtract 16 from 31 so you can simplify what you need to find. We will call the unknown number X. So 5x = 15
15/5 = 3 so X = 3
Lets plug in X
3 x 5 + 16 = 31
Makes sense!

Answer:
Both cases will give the same price
Step-by-step explanation:
The total purchase that Joshua do will be:
2* $10.98 + 1 * $11.50 + 2* $15.99 = $65.44
Let's compare the price for both scenario
1. If the tax added before discount
taxed price $65.44 * (100+6.5)% =$69.6936
discounted price= $69.6936* (100-20)%= $55.75488
2. If the tax added after the discount
discounted price= $65.44 * (100-20)%= $52.352
taxed price $52.352 * (100+6.5%) = 55.75488
Both prices will be the same since the operation in this calculation is only multiplication.
