Answer:
$70c + $50
Step-by-step explanation:
When its says $70 per car, that means you multiply 70 by the amount of cars to know how much the total car. So in your equation you would $70c and c represents the amount of cars.
You would add $50 because that's how much tips they would get. So now your equation is $70c + $50
This is the answer for the calculation
190-(50+80)t=0
190-130t=0
130t=190
t=19/13 so the trains will remain apart for 19/13 hours.
Since ironman is flying at a constant rate of 150mph he will fly:
150(19/13)≈219.23 miles in that time period while the trains are apart.
Answer:x-9
Step-by-step explanation:
Simplifying
Solving for variable
Move all terms containing x to the left all other terms to the right
Devide each side by 16
X=9
Percentage decrease formula =
difference / original x 100%
95-74=21
21/95 x 100% = 22.1052632 ≈ 22.1 ( 3sf )
