Answer:
A. 13 boxes
B. $18.00
C. $3.60
D. 0.30
Step-by-step explanation:
6 boxes = 21.60
that is 3.60 per box
A. 50.00/3.60 = 13.88 so he can purchase 13 boxes
B. 1 box is 12 ounces
60/12 = 5 boxes needed for 60 ounces. 5 x 3.60 = 18
C. One box is 3.60
D. 3.60/12 = 0.30 per ounce
A, because its the ratio between qauters and nickels
Answer:
The rate charged by first mechanic per hour= x =$85
The rat charged by second mechanic per hour =y = $70
Step-by-step explanation:
Two mechanics worked on a car. The first mechanic worked for 10 hours, and the second mechanic worked for 15 hours. Together they charged a total of $1900. What was the rate charged per hour by each mechanic if the sum of the two rates was $155 per hour?
Solution
Let
x= hourly rate of the first mechanic
y= hourly rate of the second mechanic
Derive two equations to solve for the two unknowns
10x + 15y = 1900 (1)
x + y = 155 (2)
From (2)
x + y = 155
x=155-y
Substitute x=155-y into (1)
10x + 15y = 1900
10(155-y) + 15y =1900
1550 -10y + 15y =1900
5y =1900-1550
5y=350
Divide both sides by 5
y= 70
Substitute y=70 into (2)
x + y = 155
x + (70) =155
x=155 - 70
= 85
x= 85
The rate charged by first mechanic per hour= x =$85
The rat charged by second mechanic per hour =y = $70
