26) If a shirt costs $28 and you must pay 7.5 % sales tax, how much will the tax be? A) $21.10
OB) $210.00
OC) $0.21
OD) $2.10

2.10

Step-by-step explanation:

i first got 210 ($28*7.5),  then added a decimal "." in between 2 and 1, which gave me 2.10

and you can clearly take off 210 +0.21 from your answer choices  because 210 bucks is even more than the item, and 0.21 would be like 1% sales tax

and you have 2.10 and 21.10 options left, and so I think 2.10 would be the most reasonable choice

so the final answer would be $2.10

hope this helped ^^

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
