Mark paid $8.35 per pound for fish at one market. Then he found another market that charges a member's fee of $36.90 a year plus $4.25 per pound for fish. How many pounds of fish would Mark need to buy for the total cost to be the same?

ok thats very interesting

10 - 75

step-by-step explanation:

there's nothing attached so it's most likely anything in that range.

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
