John has $132.55 in his bank account. He wants to join a guitar class that charges a $15 fee every week. John plans to take the class for 12 weeks.
If John pays for 12 weeks of guitar classes from his account, his account balance will be?

-47.5

Step-by-step explanation:

Step 1:Find out how much 12 week of guitar is 15*12=180.

Step 2:Subtract 180 from  132.55 132.55-180+-47.5.

Step 3:Answer -47.5.

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

x = 12

y = 1

for the points!
