I can’t figure this out!

a) 3.60

5.20

7.20

3.2 + .4M

b) at most, 42 minutes if only have $20

Step-by-step explanation:

minutes = 1;    3.2 + (.4)(1) = 3.60

minutes = 5;    3.2 + .4(5) =  5.20

minutes = 10;    3.2 + .4(10) = 7.20

minutes = M;    3.2 + .4M

b)  3.2 + .4M ≤ 20

.4M ≤ 16.8

M ≤ 42

at most, 42 minutes if only have $20

in the question sorry

Step-by-step explanation:

I am going to make an equation using y=mx+b alright! y=0.40x+3.20

so the first one is 3.6

the second one is 5.2

the third one is 7.2

the last one is im not sure tbh i think you make one up

part b. is 42 mins

correct answer:

i^31 = -i
