Answer:
$45
Step-by-step explanation:
THIS IS THE COMPLETE QUESTION BELOW;
For a walk-a-thon a sponsor committed to give you a flat fee of $5 plus $2 for every mile you walk. If you walk for 20 miles, what is the total amount you will collect from your sponsor at the end of the walk-a-thon?
$5 was given for participants of the walk-a-thon.
$2 was given for every miles won
Then, for "y" number of miles, the the amount that can be won is ( 2×y)= 2y
The Total amount that can be given
= (5 + 2y)
Where "y" is the miles value
Then, if you walk for 20 miles, The Total amount that can be given
= 5 + 2(20)
= 5+ 40
= $45
First, simplify each one.
9.98 x 10^6 = 9980000
7.3 x 10^7 = 73000000
Next, subtract the freight from the aircraft
73000000 - 9980000 = 63020000
Round the decimal point to the first significant digit, and place the amount of place values the decimal point moved to the left as a power sign, over 10.
63020000 = 6.302 x 10^7
6.302 x 10^7 is your answer
hope this helps
