Aloaf of bread originally priced at $3.49 has been discounted 10%.

$3.49 X .10 =  .35

the discount is .35 or 35 cents
final cost
3.49-.35= $3.14

hope this helps

Take 3.49 and multiply by.1 (3.49 x .1) then you subtract the answer from 3.49 (3.49 - answer = discounted price) it'll come out as a whole number and the decimal in the thousandths place (ex: 0.001). just round to the nearest hundredth (ex: 0.01). don't forget to add the dollar sign ($).

Idrk but i think u should figure out the n dia n then the units it will make it way more easier
