SO you get the process of multiplying the original cost by the amount in order to find out what 20% of the orginal cost is, then you add that value to the original cost in order to find the new cost.

So 20/100 x $1.50 = (20 x $1.50)/ 100 = $30.00/ 100 = $.30 )not just .30! Thirty cents. Then that thirst cents needs to be added to the original $1.50 to get the new cost.

When you keep the units (dollars, miles, inches, etc) attached to the numbers, you’ll have an easier time keeping track of where you need to add or divide. And you’ll avoid doing something silly like adding inches and miles or trying to divide dollars by cents. Units much match and when you keep them straight word problems go much easier.

There are a number of ways you can do this question to arrive to the same result. You can also multiply the $1.50 by 1.20 (the 1 represents the original price and the .20 is the 20% increase) and it will give you the new price in one step.

Good luck with your test.

2. take the amount you get from doing the first step (which should be .3 (30 cents, in money terms)) and ADD that to the original price of the candy bar ($1.50).

3. your total is $1.80. seriously, though, what a ripoff! who charges that much for a candy bar? even king size bars are, like, $1 at target (only 90 cents for me, though, because i work there.)

good luck. (can i have 10 pts. please? you know i deserve it…)

Price plus increase give you new price:

$1.50 plus $.30 = $1.80

You have to have the decimal or it will be $20.

This will give you .30 which is 30 cents.

Then add the 30 cents to the $1.50.

when dealing with money, it’s always ez to keep everything in cents if the value is under $10 and then convert it back to dollars once ur done

so 20% of 150 cents

150 x 0.2 = 30

and since ur adding (increasing) the base price by 20%

ujust add them

150 + 30 = 180

180 cents = $1.80

1.50 x 20% = 1.50 x 20 over 100 = 0.30

1.50 + 0.30 = 1.80
