Answer:
The markup rate on each box=41%
Step-by-step explanation:
The markup rate is the additional price that a good is sold at expressed as a percentage. This can be expressed as;
R={(S-C)/C}×100
where;
R=markup rate
S=selling price
C=cost
In our case;
R=unknown
S=$20.50
C=$14.50
replacing;
R={(20.5-14.5)/14.5}×100
R=(6/14.5)×100
R=41.38% rounded off=41%
The markup rate on each box=41%
That's so easy first u find a common denominator and then your answer would be 7 -4/30
