Ruby has a points card for a movie theater. She receives 50 rewards points just for signing up.
She earns 14.5 points for each visit to the movie theater.
She needs 224 points for a free movie ticket.

How many visits must Ruby make to earn a free movie ticket?

12 visits to a free movie ticket

Step-by-step explanation:

224 points for a free ticket - 50 she has for signing up = 174 points needed

174 points needed / 14.5 per visit = 12 visits to a free movie ticket

step-by-step explanation:

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
