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.
