Algebra.Com's Answer #10703 by queenofit(120)![]() ![]() ![]() You can put this solution on YOUR website! you have a jacket that cost 65 and get a discount of 30% plus the sales tax of 4%. Ok, first let me tell you that to get the cost of the jacket most people will multiply 65 * .30 then subtract the answer from the 65 to get the cost of the jacket after the discount. I will show that on the left, however, I like to save a step by multiplying by 70%. there is a 100% in everything, 100-30 gives you 70%. You are payiing 70% of the origional cost, so I multiply by this number and I don't have to subtract the answer from the cost of the jacket. I will show this on the right. When you get your cost after the discount, you have to add the sales tax of 4%. Remember to move your decimal two places to the left when changing from a percent to a decimal.\r \n" ); document.write( "\n" ); document.write( "65*.30=19.50 (discount) 65*.70=45.50 (cost after discount) \n" ); document.write( "65-19.50=45.50 (your cost after discount) 45.50*.04=1.82 \n" ); document.write( "45.50*.04=1.82 (tax) 45.50+1.82=47.32 \n" ); document.write( "45.50+1.82=47.32(your final cost) \n" ); document.write( " |
