Answer:
For this question, you need you use the unitary method or proportion. If you apply these ideas to it. You should be able to do this question. Here's my working:
Step-by-step explanation:
25ounces = $3.49
**You need to find what's the price of one ounce**
So assume it like this:
1 ounce = $X
To solve for X, you figure out how did 25 became 1. In this case, it has been divided by 25. So you do the same thing on the other side: Which is $3.49 ÷25 = 0.1396 (Price per ounce for choice A)
Choice B workings:
You apply the same method, so it's 4.79 ÷ 45 = 0.1064444444444 (Price per ounce for Choice B)
So in conclusion, <em>Choice B is cheaper. </em>

<u>Answer-</u>
The equation is 
and Julianne will begin making a profit after 168 days.
<u>Solution-</u>
Julianne's start-up cost = $52,000,
Each day, she spends = $650,
and she earns = $960 per day,
If 'd' is the number of days to overcome the start-up and daily operation cost, then
total operation cost of d days = $650d and
total student lesson fees earned in d days = $960d
∴ The equation to represent the situation is,
∴ Julianne will begin making a profit,
Answer:
1140 liters.
Step-by-step explanation:
We need 40% to top it up.
60 % = 1710
1% = 1710 / 60
40% = (1710/60) * 40
= 1140 liters.
Answer:
4/5
Step-by-step explanation:
7 1/5 - 6 2/5
We need to borrow from the 7 in the form of 5/5
6 + 5/5 + 1/5 - 6 2/5
6 6/5 - 6 2/5
0 + 4/5
4/5
