Answer:
$70.88
Step-by-step explanation:
To find sales tax, multiply the price by the percentage as a decimal.
$67.50 67.50(0.05) = $3.38
Since sales tax is 5%, its decimal equivalent is 0.05 and for the price of $67.50 you pay $3.38.
The total amount paid is the price added to the sales tax.
$67.50 + 3.38 = $70.88
Repeat these steps for each price in the sales amount column.
Answer:
68in
Step-by-step explanation:
l = 3w-16
l-3w = -16
l+w = 96
-4w = -112
w = 28 in
l = 96-28 = 68in
Answer:
y = -8
Step-by-step explanation:
Instead of trying to find the slope of the line through these two points in the usual rise/run fashion, note that y does not change as we progress from x= -5 to x= +8. This tells us immediately that this line is a horizontal one: y = -8.
