Tim bought a washing machine for a total of $651 with tax included. What was the price of the washing machine before tax if Tim
Molodets [167]

Answer:

<em>The washing machine cost $600 before tax</em>

Step-by-step explanation:

<u>Percentages </u>

The washing machine cost $651 including a tax of 8.5%.

If x was the cost of the washing machine before tax, then the tax was:

x*8.5/100 = 0.085x

It was added to the original price:

x + 0.085x = 1.085x

That is the final price, thus

1.085x=$651

Solving:

x = $651/1.085

x = $600

The washing machine cost $600 before tax

Liono4ka [1.6K]

Answer: The company will make 720 dollars (I dont know the percentage out of that though).


Step-by-step explanation: 1.10 times 1000= 1100. 35 percent of that is 385 dollars worth to charity or 350 lapel pins. 1000 minus 350 equals 650. 650 times .6 equals 390. 390 times 3 dollars= 1170 dollars. 650 times .4 = 260. 260 divided by 2 = 130, 130 times 5 dollars equals 650 dollars. 650 plus 1170= 1820. 1820-1100= 720.
