KonstantinChe [14]

Answer:

Brian's average speed: 14.73 mile/hour

The traveled distance by skiing he estimated: 11.0475 miles.

As the information provided in table, the time he spent for skiing is 0.75

=> The distance Brian traveled by skiing: 14.73 x 0.75 = 11.0475 (miles)

=> Brian's product is correct.

=> Rounding to the nearest whole number => 11.0475 = 11 (miles)

Rounding the Brian's average speed to the nearest whole number:

=> 14.73 = 15 mile/hour

Round the activity time to the nearest whole number:

=> T = 3 + 1.45 + 1.2 + 0.75 = 6.4 = 6 (hour)

Hope this helps!

The Markup percentage is mathematically given as

M=42%

<h3>What is Mark up percentage?</h3>

The markup % may be determined by dividing the gross profit of a unit (the difference between its sales price and the amount it cost to create or buy for resale) by the amount that unit originally cost. If a product sells for $12 but only costs the corporation $8 to produce it, the markup percentage for that product is 50%, which can be calculated as (12 - 8) divided by 8.

Generally, the equation for is Total cost price mathematically given as

TCP= Pay+insurance

Therefore

TCP=35.5*1.6

TCP=284/5

Generally, the equation for is Total selling price mathematically given as

TSP=89.99+7.99

TSP=97.98

In conclusion, Mark up percentage is

$M=\frac{SP-CP}{SP}*100\\\\$
