150 - 15 = 135
x -15 = 6+33 x-15 = 39 X = 54
You can't subtract 15 ones from 15 tens. The bills are all tens, so you'd have to get change first. Then you'd be subtracting 15 ones from 13 tens and 20 ones, or from 13 tens, one 5, and 15 ones.
twelve53 - 15 = 3838 + 10 = 4848 / 4 = 12Using algebra:4x -10 +15 = 534x + 5 = 534x = 48x = 12
You do this by subtracting the smaller from the larger and using a minus sign in front of the result. In this case the answer is -5.

-6 -15 = -21
You do one of two things. Take the original price, multiply it by .15, and then subtract the result from the original. Or you can multiply the original by .85 (1.00-.15) and get the reduced price immediately.
You can either calculate 15% of 34.00, which is 34.00*15/100 = 5.10 and subtract that from 34.00 to give 28.90 or you can subtract 15% from 100% = 85% and calculate 85% of 34.00, which is 34.00*85/100 = 28.90.
Pick a number between 8 and 20. double that number. subtract 16 from that answer. Multiply that result by 4. Divide that total by 8. add 15 to that answer. subtract the number that you started with.
