Answer:
180
Step-by-step explanation:
Ok first lets find out what 1/5 of 400 dollars is: 400/5= 80
So 1/5 of 400 is 80, now lets see what 2/5 is= 80 * 2= 160
Then subtract: 400 - 160= 240
we have 240 left. If he spent 1/4 of that on a vacuum cleaner then we have to: 240/4=60
He spent 60 dollars, now to find the remaining we must subtract: 240-60=180
Hope this helped ;)
So 2/5 is 0.4
0.4 of 400=160
400-160=240
240 is the remainder(what is left)
He used 1/4
1/4=0.25
240*1/4 =60
So 240-60=180
So your answer is: Mr.Ray will have $180 left.
