the clothing store where Fiona shops lowered the price of the shirts by 25%.what fraction must you multiply by to find the new price of the shirt originally priced at 18$

72

Step-by-step explanation:

1/4

Step-by-step explanation:

If a shirt is 25% off then we take that into decimal form which is 0.25 now we move that into fraction form which is 1/4. 25+25+25+25= 100 we can clearly see that there are 4 of the 25's that are needed to make 100. So this shows that it is 1/4.

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
