Karen buys 2 packages of printer paper for $5.79 each, a box of pens for $9.25. a box of paperclips for $2.29, and a
calendar for $12.50. if a 6.25% sales tax is added, what is the total cost of karen's purchase?
(show work)

I think its $37.84625 according to the working shown :)

Step-by-step explanation:

cost of paper= $5.79, hence 2 is 2 x 5.79= 11.58

pens= $9.25

paperclips= $2.29

calendar= $12.50

Total= 11.58+9.25+2.29+12.50= 35.62

6.25% sales tax on total purchase= 6.25/100 x 35.62= $2.22625

Adding the sales tax: 35.62+2.22625‬= $37.84625‬‬

the discriminant is 64 + 4*1*12 = 112

this is prime.

step-by-step explanation:

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.
