What is the selling price of an item if the original cost is $784.50 and the makeup on the item is 6.5%

I think what you meant to type is "markup".  If the markup is 6.5%, we need to increase the cost by that amount.  To find 6.5% of a number we convert it to a decimal, .065, and we add 1.00, to get 1.065.  The 1, when multiplied, gives us the original amount, and the .065 gives us the additional amount.  We multiply that by 784.5.  784.5 x 1.065 = 835.49.  The other way to do it is to just multiply by 0.065, and you get 784.5 x 0.065 = 50.99, then add it to the original amount, 784.5 + 50.99 = 835.49.

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
