The original price of mittens is $8.25. They are sold for $10.31. What is the percent of markup?

the answer is su.k.my? ? co.kc

final total: 63

step-by-step explanation:

60 times sales tax

60 times 0.05

3

60 + 3

63

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x
