Answer:
3
Step-by-step explanation:
You want total number made in 4 m onths, so adding all numbers is correct, but it is per 1 month, so multiply by 2
A because you need brain for most problems
D works
pick A and D
So domain is the number you can use
range is the output your get from inputting the domain given
so from 2≤x≤5
since it is linear, we can be sure that we only need to test the endpoints of the domain to find the endpoints of the range
sub 2 for x
y=2(2)+1
y=4+1
y=5
sub 5 for x
y=2(5)+1
y=10+1
y=11
so range is from 5 to 11
in interval notation: [5,11]
in other notation 5≤y≤11
or
R={y|5≤y≤11}
If Walter rode 12 times and 24 was deducted, then each bus ride costs :
24/12 = $ 2 per ride
