One neckace cost $32.00 and another costs $28.00 sales tax is 8 %.find total cost including tax

Hi there! So first off, let's add the prices of the two necklaces. 32 + 28 is 60. Now, let's plug in the tax. The tax rate is 8%. Let's add that to 100%, because 100% represents the whole cost. 100 + 8 is 108. That's 108%. We will multiply that percentage by the cost. 60 * 108% (1.08) is 64.8. There. The total cost is $64.80.

Step-by-step explanation:

30=5x-2x+6

30=3x+6

30-6=3x

24=3x

8=x

Checking

5(8)+6-2(8)=30

40+6-16=30

46-16=30

30=30
