Let's plug in (18,10) into each answer choice until we find the one that has it as a solution.
A) 2x - y = 26
2(18) - 10 = 26
36 - 10 = 26
26 = 26
Your answer is A.
I'll just do the rest to show that you the they are incorrect.
B) x + y = 18
18 + 10 = 18
28 ≠ 18
C) 2x - 2y = 36
2(18) - 2(10) = 36
36 - 20 = 36
16 ≠ 36
D) x - y = -28
18 - 10 = -28
8 ≠ -28
Your answer is A) 2x - y = 26.
It would go after four as it equates to about 4.2
<span>For every car
Mike earns------------------ >$200 plus 3% commission</span>
3 cars-----------------
> $200*3+$32,343*0.03=600+970.29=$1570.29
Total earnings
for a week is $1570.29
1/10 * 4/10 = 4/100 divide both by 4 it'll be 1/25
