Tyrell is gearing up for the football season and decides to purchase some items online. He has a promotional code for a one time 10offanypurchaseof50 or more. Tyrell orders 2 new jerseys at 32.89eachandahatfor23.99. Tyrell pays 7% sales tax on his purchase, but pays no shipping charges. What is the total of Tyrells online purchase?

a. 50.16
b.79.77
c. 85.35
d.96.05

c. 85.35

Step-by-step explanation:

We have been given that Tyrell has a promotional code for a one time 10 off any purchase of 50 or more. Tyrell orders 2 new jerseys at 32.89 each and a hat for 23.99.

Let us find cost of 2 jerseys by multiplying cost of each jersey with 2 as:

Now we will add the cost of hat to cost of 2 jerseys to find total cost.

Now we will use promotional code to $10 off.

We are also told that Tyrell pays 7% sales tax on his purchase. So total cost will be 79.77 plus 7% of 79.77.

Therefore, the total cost of Tyrell's online purchase is 85.35 and option 'c' is the correct choice.

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
