You have $500 in savings accounts. over a 2 month period, you make 9 withdrawals of $30 each. what is your balance

9 * 30 = 270

500-270 =230

oh easy just take 9 times 30 than subtract 500

which is 230

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^
