Answer:
$75.6
Step-by-step explanation:
Multiply the model car's price by 105% (or 1.05) to find the total price.
$72 * 105% = $75.6.
Pick any two points
(0, 3), (-1,9)
Find slope (y2-y1)/(x2-x1)
(9-3)/(-1-0) = 6/-1 = -6
Y = -6x + b
Plug in a point
3 = 0 + b, b= 3
Final equation: y = -6x + 3

All you have to do is look at the graph.
5 gallons of gas is $8.80, let’s figure out how much one gallon is. 8.80/5=$1.76.
1.76•6=10.56 check
1.76•7=12.32 check
Now let’s figure out how much 10 gallons of gas cost.
1.76•10=17.6
10 gallons of gas costs $17.60
Answer: it will take them 28 minutes to fill the tank.
Step-by-step explanation:
The first pipe alone can fill the tank in 84 minutes. This means that the rate at which the first pipe fills the tank per minute is 1/84
The second pipe can fill the tank in 42 minutes by itself. This means that the rate at which the second pipe fills the tank per minute is 1/42
If they work together, they would work simultaneously and their individual rates are additive. This means that their combined rate of filling the tank would be
1/84 + 1/42
Assuming it takes t hours for both pipes to fill the tank working together, the working rate per minute would be 1/t. Therefore,
1/84 + 1/42 = 1/t
3/84 = 1/t
t = 84/3
t = 28 minutes
