Since four friends should make a profit of $400 each, the total undivided profit should be $1600. Profit (P) is the difference between the total revenue (R) and the total cost (C).
P = R - C ; R = P + C
Substituting the known values,
R = $1600 + $525 = $2125
Thus, the total income that the friends should earn is $2125.
Answer:
Range = <em>18</em>
Step-by-step explanation:
5, 7, 8, 8, 15, 23
Range: Highest value (number) - Lowest value (number) = final answer
Range: 23 - 5 = 18
First, change the fraction (decimal and percent) into gallon
Martha used 17% of the total oil, that means
Martha = 17% × 8 gallons
Martha = 0.17 × 8 gallons
Martha = 1.36 gallons
Brett used 0.18 of the total oil
Brett = 0.18 × 8 gallons
Brett = 1.44 gallons
Mike used 0.7 gallons
Second, compare the number of gallon they used
1.36
1 acts as ones
3 acts as tenths
6 acts as hundreths
1.44
1 acts as ones
4 acts as tenths
4 acts as hundreths
0.7 or 0.70
0 acts as ones
7 acts as tenths
0 acts as hundreths
Compare the ones, 1.44 and 1.36 both have 1 as the ones, however 0.7 has 0 as ones. Because 1 is greater than 0, 1.44 and 1.36 are greater than 0.7.
Now compare the tenth, 1.44 has 4 as the tenths, and 1.36 has 3 as the tenths. Because 4 is greater than 3, 1.44 is greater than 1.36.
1.44 > 1.36 > 0.7
Brett > Martha > Mike
Brett used the greatest amount of oil
