$16.50 since you want to multiply the budget per person by how many people their are
Difference between 60 and 45 is 15 so $15 in 10 cent would be 150 so 150 miles . Answer: you would need to drive more than 150 miles for plan b to save money:)
Y = 3x + b
Now plug in points
-7 = 3(-1) + b
-7 = -3 + b
b = -4
The y intercept is -4
Put it into standard form so you would have
27x10¯6 divided by 9x10¯6
Then you can divide the numbers so 27/9 = 3
Then to divide the powers you just take them away so - 6--6 = - 6 +6 = 0
Therefore the answer is just 3
