Answer: they would leave a tip of
$4.581 and their total bill would be $30.031
Step-by-step explanation:
Brad and his mom went out for lunch and the bill came to $25.45. His mom wanted to leave a 18% tip. This means that the amount of the tip that she wanted to leave is 18% of the bill that came. Therefore
Amount of tip = 18/100 × the bill that came.
Amount of tip = 0.18×25.45= $4.581
So they would leave a tip of $4.581
behind.
The total bill would be sum of the original bill + sum of the amount of tip that they want to leave behind. Therefore, it becomes
25.45 + 4.581 = $30.031
Answer:
problem 2: 40 pounds on mars
Step-by-step explanation:
formula for direct variation is y=kx. if i assume that the weight on mars is x and y is earth, we can input these numbers to find k. the equation is (using the given numbers) 150=k50. using isolation, we know k is 3. for the main problem, we can input our givens again to find the answer. 120=3x. isolation again, x=40
Answer:
30 = 5y - 4x or 6 + (4x/5) = y (in mx + c = y form)
Step-by-step explanation:
slope =
- / -
now, = 2
= -5
insert the values of these two in the slope formula and equate it with 4/5.
by cross multiplication, obtain equation.
the equation is 30 = 5y-4x.
hope this helps you!
