Mathematics is math, geometry, algebra, calculus
Answer:
$ 71.5
Step-by-step explanation:
firstly kilometer to meters
<em>1 km = 1000 m </em>
therefore 3 km = 3000m
for the first 500 = $40
hence deduct the 500 from 3000m
3000 - 500 = 2500
now find out how many 300m go into 2500
2500 / 300 = 8.33
which is rounded up to 9
therefore the total amount is :
40 + 9 * 3.5
<u>= $71.5</u>

Answer:
A. 2 4/5
Step-by-step explanation:
To find how many hours she worked for $210, you must get the amount of money she gets in 1 hour.
Because she charges $43 dollars every hour, and fines a fee of $30 flat, we must add both of the amount to get how many she earns in 1 hour.
So:
$45 + $30= $75
She earn $75 in 1 hour.
Next, divide $210 dollars that she earned for working for hour(s) to the amount of money she earned in 1 hour to find how many hours she worked.
So:
$210 ÷ $75= 2.8 hours
The answer is 2.8 hours
Because the given answers is in fraction, we must change the decimal into a fraction.
To change a decimal into a fraction, you must place the decimal over its place value.
Because 8 in the decimal 2.8 is in the tenths place, you must place it over 10
So:
2.8 into a decimal is 2 8/10
Simplify (only simplify if possible):
Divide 8 and 10 to their GCF which is 2.
So:
8 ÷ 2= 4
10 ÷ 2= 5
So the fraction and the answer is now:
2 4/5
I hope this helps! I'm sorry if it's wrong and too complicated.
