Answer:
$163.85
Explanation:
Since the cost of the couch is $113.00 then this is the original 100% price. To find a 45% mark up then find 145%. Remember 100+45 = 145. To find the price set up a proportion with these values:
![(x)/(113)=(145)/(100)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/dijdp6i4jdplur73ea1ard5gr3noegfhqy.png)
Solve for the price by cross multiplying numerator with denominator.
x(100) = 113(145)
100x = 16385
x= 163.85
