Answer:
a = $0.95
Step-by-step explanation:
The cost of a sharpener is 'a', and the cost of a folder is $2.80 more, so is a+2.80. The total cost of 4 sharpeners and 7 folders is ...
4a +7(a+2.80) = 30.05
11a = 10.45 . . . . . . . . . . . subtract 19.60
a = 0.95 . . . . . . . . . . . divide by 11
The cost of a sharpener is a = $0.95.
You are adding 2 each time.
You are trying to find the 30th term, in which 4 are shown.
Subtract 4 from 30
30 - 4 = 26
Multiply 26 with 2
26 x 2 = 52
Add 52 to the last number given (0)
0 + 52 = 52
52 is your answer
hope this helps
