Answer: A. 30+(-12)+70
Step-by-step explanation:
Commutative property of addition is given by : a+b = b+a , where a and b can be any expression of real numbers.
It basically changes the order of the so that simplification of any expression becomes easier.
In A. we use this property as
30+(-12)+70 = 30+[(-12)+70]
= 30 + [70+(-12)] [we switched order of (-12) and 17]
= 30+70-12
= 100-12
= 88
The rest of the expression already arranged accordingly, there is no need to apply commutative property to change the order of the numbers.
So the correct option is A. 30+(-12)+70.

Answer:
19 players
Step-by-step explanation:
The total being spent is ...
bus cost + (per player cost) × (number of players) = total raised
250 + 25.85p = 741.15
25.85p = 491.15
p = 491.15/25.85 = 19
The team could bring 19 players to the tournament.
120 - 96 = 24
Now we have to find what percent of 120 24 is.
x × 120 = 24
x = 0.2
0.2 means 20%.
The discount is 20% off.
1) Gathering the data
P=$6200
F=7310
t= 3 yrs
2) Since it is a simple interest, it is a linear application. So we can find it using this formula:
