Explanation: there are 3 cups of bagel chips for every 3 cups of pretzel chips
A = number of calls the first evening
b = = number of calls the second evening
c = number of calls the third evening
we know that she received a total of 99 calls, thus whatever "a", "b" and "c" are, we know that
a + b + c = 99.
"<span>The third evening, she received 4 times as many calls as the first evening"
c = 4a"</span><span>The second evening, she received 9 more calls than the first evening."
b = a + 9</span>

<span>
and surely you know how much that is. Well, she got that many the first night.
how many the second night? well b = a + 9
what about the third night? well, c = 4a.</span>
