Answer:
<em>$4.84</em>
<em></em>
Step-by-step explanation:
Given that
For delivery within mi, charges = $1.25
For delivery within mi -
mi, charges = $1.70
For delivery within mi - 2 mi, charges = $2.15
and
so on.
i.e.
For delivery within 2 mi - 2 mi, charges = $2.60
For delivery within 2 mi - 2
mi, charges = $3.05
For delivery within 2 mi - 2
mi, charges = $3.50
For delivery within 2 mi - 3 mi, charges = $3.95
For delivery within 3 mi - 3 mi, charges = $4.40
So, every 0.25 mi or mi increase in distance, there is an increase of $0.45 in the charges.
It is given that there is increase of 10% in the rates.
i.e. for every 0.25 mi increase in distance, there is an increase of 0.45*1.10 = $0.495 in the charges.
The distance of miles lies within the range 3 mi - 3
mi.
So actual charges after increase of 10%
