Sales Tax in the state of Mathland is 8.5%. After buying school supplies, your total was $81.42, before tax. How much do you end up paying including tax? (SHOW WORK.)

A: $6.92
B: $74.50
C: $88.34

A

Step-by-step explanation:

8.5% of 81.42

8.5                 81.42           692.07

   X       =    

100                     1                 100

divide 692.07/100 which gives you 6.9207

if you round it to the nearest hundredth you get 6.92

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
