Sean has $75 to spend on cds. if each cd costs $6.98, about how many cds can he buy?

He can buy 10 CD's

Step-by-step explanation:

Cost of 1 CD = $6.98

Let x be the no. of CD's

So, Cost of x CD's = $6.98 x

We are given that Sean has $75 to spend on CD's.

So, He cannot spend more than $75

So,

So, he can buy 10 CD's

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
