Answer:

Step-by-step explanation:

Add the given numbers to the last recorded temp and see what is closest to 100 degrees.

95.5 + 6.5 = 101.5

95.5 + 6.6 = 102.1

95.5 + 5.5 = 101

95.5 + 5 = 100.5

So the closest to 100 degrees would be 5.

Answer:

Single Equivalent Discount % on final price = 41.58%

Explanation:

The grill was initially priced at $769.99 and was discounted to $550.54 which is 28.5% ((550.54/769.99)-1)*100

and then further discounted by 18.3% ((449.79/550.54)-1)*100 to $449.79.

but if we want to get the single discount rate for $449.79 (final price), we have to compare it with very first original price of $769.99 so the formula will be:

((449.79/769.99)-1)*100 = 41.58% which shows the actual discount % versus the original price of the grill.
