5 lily had $20. she spent d dollars for a present for camille.
a write an expression that shows the number of dollars lily had left.

b explain how you found your answer.
what’s the answer

$5.41

step-by-step explanation:

$20 - $14.51 = $5.49.

b is the right answer

to find the unit price of an object, you divide the price by object. you are trying to find out how much an object cost per unit.

for instance, lets say you have 50lb of ice cream(object) that cost 8.00 dollars(price). to find the unit cost, we take the 8.00 and divide it by 50, which will give us .16 cents per pound. we can check this by multiplying .16 by 50 = 8.00

so

object = e2

price = d2

unit price = c2

formula for c2:

=d2 / e2

so in my example about ice cream, we would have the following.

e2 = 50

d2 = 8.00

c2 formula:

=d2 / e2
