Answer:
a. answer choice c
b. 20301
Step-by-step explanation:
You first need to understand a formula for finding the sum of consecutive integers starting from one: (m*(m+1))/2, m is the biggest number in the set.
a. The biggest number in your set is 100, so we plug in 100 for m and solve:
100*101/2=50*101=5050
b. Same thing. Use the formula t plug in 201 for m:
201*202/2=201*101=20301
The only reason you have the picture next to your question is to prove the formula (m*(m+1))/2.

Answer:
$89.64
Step-by-step explanation:
First, you want to find your unit rate.
To do that, simply just divide what you know (cost/amount):
29.88/12
= 2.49
This means that one role of tape costs $2.49.
Now that we know that, you can simply just solve for value "c":
c = 2.49(36)
c = 89.64
