Answer: 21 dollars was his bill before the tip
Step-by-step explanation: 4.20 is 20% of what he paid with no tip included. This means you can set up an equation like this.
4.20 = .2x This means that $4.20 is (is means =) 20% of (of means multiply) x (which is the unknown factor).
Answer:
Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles. The field emerged in the Hellenistic world during the 3rd century BC from applications of geometry to astronomical studies.
You need to find the total distance and the total time. The total distance is two times the distance to school, 2d.s=d/t=>t=d/sWhere s is speed, d is distance and t is time. So the time taken to get to school is:d/s1and the time taken to get back is:d/s2so the total time is:d/s1+d/s2=d(1/s1+1/s2)So, as speed = distance/time, divide the total distance by the total time:2d/d(1/s1+1/s2)=2/(1/s1+1/s2)=2/(1/20+1/40)=80/3≈26.7km/hr
26 adult tickets = $12 (cost of an adult movie ticket) • 26 = $312
There were $312 dollars worth of money sold from the adult tickets that were sold for the 10PM show.
$600 - $312 = $288
This means that there were $288 dollars worth of money sold from children’s tickets for the 10PM show.
Since each children ticket is $8, you would do
8x = $288
(X IS HOW MANY CHILDREN TICKETS THAT WERE SOLD)
Once you do that, you would simplify it by dividing 8x by 8 which would give you x by itself and do the same thing for the other side as you have to do the same for both sides of the equal sign. So, you would do $288 divided by 8 and get 36.
x = 36
To check our work, we will substitute the value of x into the equation
8(36) = $288
288 = $288
Therefore, there were 36 children tickets sold for the 10PM show.
