12. Since k is constant we can find k when given any point by dividing the y-coordinate by the x-coordinate. For example if y varies directly as x, and y =6 when x=2, the constant of variation is k==3. The equation describing this direct variation is y=3x.

Julie's savings account has a balance of $57.85 in January. By March, her balance is 4 times as much as her January balance. Bet

January . . . $57.85

March . . . . 4 times as much = 4 (57.85) = $231.40

Deposit  78.45 more . . . ($231.40 + 78.45) = <em>$309.85</em> .

Notice that "interest" is never mentioned anywhere in this problem.
In other words, it doesn't matter whether Julie's savings account is
in a bucket in the basement, a mayonnaise jar on the porch, under
her mattress, or in a bank that pays no interest.

Without interest, $309.85 is what she <em><u>does</u></em> have<em><u /></em> in November, which
is about right for savings accounts in banks these days.

What her balance <em><u>should</u></em> be in November is an entirely different subject.
