Tim has an after-school delivery service that he provides for several small retailers in town. He uses his bicycle and charges $1.25 for a delivery made within 1 1/2 mi, $1.70 for a delivery of at least 1 1/2 mi but less than 1 3/4 mi, $2.15 for a delivery of at least 1 3/4 mi but less than 2 miles, and so on. If tim raised his rates by 10% what would he be paid to deliver a package 3 1/8 miles

$4.84

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%

answer: 7 x 2/5 = 2.8 hours, is your answer. your welcome! : 3

step-by-step explanation: first work out how long it took to hose 1/7 of the lawn which is 2/5 hours. times that by 7 to get the whole lawn.

sorry i don't know the other answer. i didn't learn what a proportional relationship is.

a. (14,375+570)(5.3) b. 158,417$

step-by-step explanation:

a. you are basically just setting up the equation. f= amount of debt hence 14,375. g= how much she is borrowing from her parents weekly hence 570 and t= the interest on her debt. creating the equation.

b.   14,375+570= 14,945

      14,945 x 5.3 = 79,208.5

      79,208.5 x 2(years) = 158,417(answer)
