You are buying shoes online. The selling price is $29.99. Round to the nearest penny, if necessary.
a. The sales tax is 6.5%. what is the total cost?
b. The cost of shipping is 15% of the total cost. what is the total cost plus shipping.
c. If the total cost plus shipping is greater than $35, then your receive a 10% discount off the original selling price. Do you qualify? If so, what is the new total cost plus shipping?

(a)=>sales tax= 6.5% of total cost which is equal to (6.5*29.99)/100

= $1.95

(b)=>shipping = 15% of total cost which is equal to (15*29.99)/100 = $4.5

total cost plus shipping = 29.99+4.5= $34.49.

(c)=>if $34.49 is greater than 35%, that is if $34.49 is greater than (35*29.99)/100 which is equal to $10.5, therefore we see that total cost plus shipping is greater than 35%. So we receive 10% discount of $29.99, where 10% discount of $29.99 is $2.999, therefore the new cost will be $26.99. If so, the new total cost plus shipping is $26.99+$4.5, which is equal to $31.49.

therefore, the new total cost plus shipping is $31.49.

the median here is 25. your lowest value is 14 and highest value is 48. to find the third quartile, find the medium number in between 25 and 48 which would be 42 i believe.
