Answer:
25%
Step-by-step explanation:
The discount was $2.50. Dividing $2.50 by $10, we get 0.25, or 25%
We know that
a1=1
a2=3
a3=9
a2/a1=3/1----> 3
a3/a2=9/3----> 3
<span>common ration r is equal to 3
number of terms n is 12
The </span><span>Sum of geometric series is given by the formula
</span>Sum=a1*[1-r<span>^n]/[1-r]
</span>Sum=1*[1-3^12]/[1-3]-----> Sum=[1-3^12]/[1-3]----> [3^12-1]/[3-1]
<span>Sum=531440/2-----> 265720
the answer is
265720

Answer:
$8.90
Step-by-step explanation:
$2 for the 1/4 mile. That leaves 5 3/4 more miles until 6 miles. He charges 30 cents for each additional 1/4 miles, and there are twenty-three 1/4ths in 5 3/4. So, 23*30=690, which is basically $6.90 because it's 690 cents.
$6.90+$2=$8.90
