Answer:
The cost of 10 balls is [tex]P=\$13.50[/tex]
Step-by-step explanation:
Let
n -----> the number of balls used
P ----> the total price in dollars
we have
[tex]P=0.80n+5.50[/tex]
This is a linear equation in slope intercept form
where
the slope is
[tex]m=0.80\ \frac{\$}{ball}[/tex]
[tex]b=\$5.50[/tex] ----> the coordinate y of y-intercept
To find out the cost of 10 balls, substitute the value of n=10 in the linear equation and solve for P
so
For n=10
[tex]P=0.80(10)+5.50[/tex]
[tex]P=\$13.50[/tex]
Answer:
Therefore, the price of 10 multiply by 0.80 balls is $ 8.
Step-by-step explanation:
The price of each ball is the relationship's rate of change, which in linear relationships is represented by the slope of the graph.
The equation for PPP is in slope-intercept form, so the slope of the graph is 0.80 . This means that each ball costs $ 0.80 dollar
