Rohan had ten dollars. he bought x pounds of potatoes which were on sale for 40% off the original price. write and expression that represents the amount of money rohan had left in simplest terms.

Let y represent the original price of potatoes per pound

Since he purchased the potatoes at 40% off the original price, this can represented as y*(1-0.4)

Now the weight of potatoes he purchased is x pounds, the total cost of these potatoes can be represented as x*y*(1-0.4)

The total amount of money he had is $10

The amount of money left over can be represented by the expression =

10 - x*y*(1-0.4)

where "x" is the weight of potatoes in pounds and "y" is the original price per pound of potatoes

6(h+1)/2=a

a=area
