2 × (26,300 - 3,200)
If the population is 3,200 more than half of last year's, you can subtract 3,200 to get half of last year's. Then, just multiply by two to double it (because 2 × 1/2 is a whole or 1)
Hope this helps!
Answer:
See below.
Step-by-step explanation:
You have to find the unit price.
1750/7=250
Now, multiply the unit price by the desired amount.
250*12=3000
So, 12 calculators will cost 3,000.

40 students
12-A
18-B
40-12=28
28-18=10
10/40 did not vote.
25% did not vote
10 is one fourth of 40
fourth of 100% is 25%
The cost of manufacturing 
units is
, where 
cost per unit and 
fixed cost.
Given that
Subtract the second equation from the second,
The variable cost per unit is 
.
From the given problem, it says show how to make a ten to solve 13-7.
Subtracting 13 to 7 gets 6. In order to get a 10, subtract 10 by 6. 10-6 = 4.
So, you need to add 4 in order to make a ten.
