Answer:
She spent $33 dollars
Step-by-step explanation:
3 times 2.75 equals 8.25
4 times 5.50 equals 22
1 times 2.75 equals 2.75
8.25+22+2.75= $33
N = 1 corresponds to day 1
n = 2 corresponds to day 2
...etc etc...
n = 21 corresponds to day 21
Plug in n = 21
a_n = 100 + (n-1)*4
a_21 = 100+(21-1)*4 ... replace every n with 21
a_21 = 100 + 20*4
a_21 = 100+80
a_21 = 180
