Your variable is r for the number of rooms
So your equation is 395= 35*r + 80
First subtract 80 from both sides of the equation
315 = 35r
Next divide 35 from both sides of the equation
And your final answer is 9 rooms in total he sprayed.
Total cost = 35(#ofrooms) + 80
Answer:
{0, 2, 4}
Step-by-step explanation:
satisfies these criteria: 0 is less than 1, and 0+2+4 = 6.
28+22+29+ 21 (your answer) = 100 divided by 4 (the amount of numbers used) = 25 (average)
Answer:
1. $0.24
2. 89.2 miles
Step-by-step explanation:
To get the unit price, divide the total price by the amount that was purchased.
1. 3.12/13 = $0.24
For the second one, get the distance traveled per hour first then multiply by 8.
22.3 / 2 = 11.15
11.15 x 8 = 89.2
