Jack collected 18 ten-dollar bills while selling tickets for a show. He gave 16 of the bills to the theater and kept the rest. How much money did he keep?

$20

Step-by-step explanation:

18 ten-dollar bills = 18×10

18×10=$180

He gave 16 of the bills = 16×10

16×10=$160

Now, the question is asking how much money he kept. This refers to the total amount of money, not just how many bills he kept.

(18×10) - (16×10)

180 - 160 = 20

Therefore, Jack kept $20 from selling the tickets.

im not sure

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
