If the price of a loaf of bread was $3.20 but went up by 17.5%, what price should it be now?

$3.76

Step-by-step explanation:

OG PRICE: $3.20

Goes up 17.5%

17.5/100 = .175

3.20 x .175 = .56 ( How much it went up)

3.20 + .56 = $3.76

wholesale price is the initial price before markup. retail price comes after the markup.

a price of 8 bucks that's marked up by 100%   is

formula: initial price + (percent markup in fraction/decimal)(initial price)

8+(1)(8)

8+8

16

retail price is $16.

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
