If a fit-bit hr sold for$98 and was discounted 18% and then a sales tax was applied of 9.5%. find the total cost

$87.99 is the total cost.

Step-by-step explanation:

Step 1: Although you discount 18% of $98, you still have 82% of the original cost included. Multiply 98 by 82% to get 80.36.

Step 2: Now, because you are multiplying the whole cost, add 100% to 9.5% to get 109.5%. Multiply 80.36 by 109.5% to get the answer. 80.36 * 109.5% (1.095) is 87.9942 or 87.99 when rounded to the nearest hundredth.

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
