Eva makes a few dozen cupcakes and sells them for $8 a dozen. which function represents the relationship between the money eva earns, m, and the number of cupcakes she sells, c? a. f(c) = c × 8. b. f(m) = c × 8. c. f(c) = m × 8. d. f(m) = m × 8. e. f(m) = c × m

We let c represent the number of dozen cupcakes in which the problem says that the cost of each cupcake is $8 per dozen. In this case, the money earned by Eva should be a function of the number of dozen cupcakes. In this case, the expression that represents this is  A. f(c) = c × 8

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.

The point (5, 10) will work for the rule y=x+5.y= 10 x= 510=5+510=10therefore the ordered pair (5, 10) works for the rule
