Answer:
profit%=35%
Let cp be x
profit =$280
To find cost price of a refrigerator use formula
profit%=profit/cost price *100
35%=$280/x*100
35%=$28000/x
35*x=$28000
x=$28000/35
x=$800
now to find the selling price of a refrigerator use formula
selling price=cost price +profit
=$800+$280
=$1080
Step-by-step explanation:
therefore the cost price of a refrigerator is $800 and selling price is $1080
50 x 1% = 0.5
because 1% is equal to 1/100 so 50 x 1/100 is equal to 50/100 or 1/2 which is equal to 0.5
So let n be the smallest number. To have consecutive even integers each number goes up by 2 so n, n+2, n+4, n+6, n+8.
Therefore, n+n+2+n+4+n+6+n+8=290
5n+20=290
5n=270
n=54
