How much will you need to save to purchase a $100 item in a state with a 6.5% tax rate?

$93.89

Step-by-step explanation:

Work backwards -> 1.065x=100

x=$93.89

$106.50

Step-by-step explanation:

Take 100 and multiply it by 6.5%. This will give us 6.5, the amount of tax to pay. Then add 100 to 6.5 giving you the total of $106.50.

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)

the least common denominatore of 7 and 2 is 9

step-by-step explanation:

7+2=9
