First, we have to add the fractions.
1/3 + 1/4 = 7/12
12 - 7 = 5
She earns 5/12 of her paycheck on Wednesday
M(slope)= -5/4 point-slope(y-y1=m(x-x1)) so it would be y-5= -5/4(x+4)
Since you keep proportional dimensions, the proportion between the old and new dimensions must be the same. So, if we call the new height
, the preservation of the width/height ratio is written as

Solving the proportion for
yields

Look at it this way 1(700)*1(20). can u do it now?
