Question

A person earned $600 a week for 15 weeks. He puts $120 into a savings account each of these weeks and spends the rest. How much did he spend during the 15 weeks?

Answer 1

120×15=x

600×15=y

y-x= your answer

Answer 2

K so first lets just find what he got in total.  SO 600*15=9000

So in total he made 9000

Now we need to find how many he put in savings. So 120*15= 1800

So he kept 1800 of his 9000. To find how muck he spent we just subtract. SO 9000-1800=7200

So he spent $7,200 in 15 weeks
Hope that helped:)
