Answer:
$85.60
Step-by-step explanation:
We add the percentage of sales tax to the total. This means we are paying 100% + 7% tax, or 107%.
107% = 107/100 = 1.07; this gives us
80(1.07) = 85.60.
<span>It is estimated that 5000 live bacteria existed in the sample before treatment. After each day oftreatment, 40% of the sample remains alive. Which best describes the graph of the function thatrepresents the number of live bacteria after x days of treatment? f(x) = 5000(0.4)x, with a horizontal asymptote of y = 0 f(x) = 5000(0.6)x ...</span><span>

Answer:
On sale at a deficit of -20% from the original price is saying that the item is at 80% of its original value.
Converting percentages using decimals is a very easy way to fine original values.
So:
$76.80 = 80% of the original value
convert the 80% into a decimal = 0.80
The maths:
$76.80 ÷ 0.8 = $96.00
$96.00 = the original value.
