Answer:
C. C = 0.75b + 3.78
Step-by-step explanation:
We know that Kalvin sells bottles of water, in which he charges 75 cents for each one, with an additional 3.78 for ice.
Easily enough, we know that 0.75 has to be with a variable, because there is 75 cents being charged "per bottle." Therefore look for an answers that has the expression "0.75b".
This would leave us with "C."

Answer:
158
Step-by-step explanation:
The sequence is 3, 8, 13, ..., 253.
Going backwards, it's 253, 248, 243, ..., 3.
First term is 253, common difference is -5.
The nth term is:
a = 253 − 5(n − 1)
The 20th term is:
a = 253 − 5(20 − 1)
a = 158
