First add the prices of the original books.
2.5+4.95+6=11.45
Find 20% of 11.45
=2.29
Therefore I saved $2.29
Answer:
The rule is "add 5, add 10, add 20" and the rule keeps doubling.
First club
y= 40 + 10x y= 40 + 10(8) =120
Second club
y= 15x y= 15(8) =120
now plug a number of the answer choices in each equation until you get the same result for both
The answer is C
I think the two numbers are four and three. Hope this helps.
