## iluvreading 2 years ago Price of the item: \$12.99 what is the item price with a 5 % sales tax.

1. satellite73

$$12.99\times 1.05$$ and a calculator

do i use part=percent x whole

3. ParthKohli

Calculator's for newbs.

4. ParthKohli

I approximate stuff.

5. satellite73

you can estimate 10% of 13 is 1.3 so 5% of 13 is .65

6. ParthKohli

$12.99(1 + 0.05) = (13 - 0.01)(1 + 0.05)$FOIL.

7. ParthKohli

That one is, if you don't want to approximate. ^

i think approximating is easier

9. ParthKohli

It always is.

soo do i add .65 to 12.99

11. ParthKohli

Yes.
