Answer:
x+y =13
10x + 9y =122
Step-by-step explanation:
Hi, to answer this question we have to write a system of equations:
The sum of the hours he worked washing cars (x) and the hours he worked walking dogs(y) will be equal to the total hours worked (13)
For the second equation the product of the number of hours he worked washing cars(x) and the price per hour ($10) plus the product of the number of hours he worked walking dogs (y) and the price per hour ($9) will be equal to the total amount earned (122)-
So, the system of equations is:
Where:
x: number of hours Jose worked washing cars
y: number of hours Jose worked walking dogs
Answer:
The average price per square yard is $8.00
Step-by-step explanation:
From the question
849 yd² = $6,796
1 yd² = x
Cross Multiply
849 yd² × x = 1 yd² × $6,796
x = 1 yd² × $6,796/849yd²
x = $8.0047114252
Approximately = $8.00
Therefore, the average price per square yard is $8.00
