The price of all gallons 12*(2.89)=$34.68
a) the price of the granola bars 2*(1.59)=$3.18
b) 1 apple=$0.89
c) 2 bottles of vitamin 2*(1.39)=$2.78
a)+b)+c)=6.85$, the 7.5% of this amount is $0.51
so finally, Leon should have paid $6.85+ $0.51+ $<span>34.68 =$42.04

but he paid $44.64, so the true answer is C) he <span>paid $2.60 too much ($44.64 - $42.04 =$2.60)</span>
Answer:

Step-by-step explanation:
The sum of an infinite geometric series is expressed according to the formula;
where;
a is the first term of the series
r is the common ratio
If the sum of an infinite geometric series is three times the first term, this is expressed as 
Substitute
into the formula above to get the common ratio r;


open the parenthesis

subtract 3 from both sides

<em>Hence the common ratio of this series is </em>
