Answer:
Yes
Step-by-step explanation:
for pens you are adding 3 each time
for boxes you are adding 1 each time
it is correct because they all have the same unit rate
3/1=3
6/2=3
9/3=3
12/4=3
I think is you just need to multiply that input number just to get the right answers
Example: 5 multiply by 5 equal 25

Ok let's start with question 1.
1. The equation is given. If she advices 360 people each week for 4 week she earns...
4(80+360(15)/100) = $536
2. In this problem instead of evaluating M we solve for n with M given.
140=80+15n/100
n=400 people
3. The new equation will still follow the same format.
M=65+21n/100
4. This will be the intersection point of the two lines. So when does...
80+15n/10=65+21n/100
We just have to solve for n.
-0.06n=-15
n=250 people
5.40/x=0.75/1
cross multiply:
0.75x=5.40
divide:
0.75x/0.75=5.40/0.75
x=$7.20
just to check:
5.40/3=1.8
1.8*4=7.2
the answer is $7.20 for 1 hour
