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%

Answer:
DE = 4.24
Step-by-step explanation:
The diagram is not shown; However, the question can still be solved without the diagram.
Having said that,.
Given that
DF = EF = 3
This implies that DE is the hypothenus and will be solved using Pythagoras theorem.
DE² = EF² + DF²
Substitute 3 for EF and DF
DE² = 3² + 3²
DE² = 9 + 9
DE² = 18
Take Square Root of both sides
DE = √18
DE = 4.242640687119285
DE = 4.24 (Approximated)

About 95% of a normal distribution lies within two standard deviations of the mean, so 5% lies without, and since the distribution is symmetric, 2.5% lies to either side. This means
