Answer:
x = 5
z =2
y =4.4
Step-by-step explanation:
y varies directly as x
y = kx
and inversely as z
y = kx/z
Putting in the numbers in the first line of the table, we can solve for k
13.75 = k * 25/4
Multiply by 4
13.75*4 = 25k
55 =25k
Divide by 25
55/25 = 25k/25
2.2 = k
Now we can fill in the table
y = 2.2 x/z
Row 2 we need to find x
1 = 2.2 x/11
Multiply by 11
11 = 2.2 x
Divide by 2.2
11/2.2 = 2.2x
5 =x
Row 3 we need to find z
18.7 = 2.2 *17/z
18.7 = 37.4 /z
Multiply by z
18.7z = 37.4
Divide by 18.7
18.7/18.7z = 37.4/18.8
z =2
Row 4 we need to find y
y = 2.2 *10/5
y = 22/5
y =4.4

Answer:
The answer to your question is:
1 golf ball = $0.75
1 can of tennis balls = $1.25
Step-by-step explanation:
Data
5 dozen golf balls for $45.00
2 dozen cans of tennis balls = $30.00
Golf
# of golf balls = 5 x 12 = 60
60 balls --------------- $45
1 ball ----------------- x
x = 1x 45/60 = $0.75
Tennis
# of cans of tennis balls = 2 dozens = 24 cans
24 cans --------------------- $30
1 can ---------------------- x
x = 1 x 30 / 24 = $1.25
