16 tens=160, 160+15 ones=175. The answer is 175.
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.
15 638 can be made with 1 ten, 5 ones, 6 hundreds, 3 tens, and 8 ones; 1 ten, 8 ones, 6 hundreds, 3 tens, and 5 ones; or 6 ones, 5 hundreds, 3 tens, 8 ones, and 1 ten.
150 - 15 = 135

(9*10)+(15*1) = 105

the tens place is on the left for example the # 15 1 is the tens and 5 is the ones
150 - 15 = 135
If I'm figuring this correctly, 16*10 = 160 and 15*1 = 15, so 160 + 15 = 175.

150 = 15 x 10
