Answer:

4 months

Step-by-step explanation:

<u>Club A</u>

<em>registration fee: </em>$0

<em>monthly fee</em>: $105

<em>After</em><em> </em><em>every</em><em> </em><em>month</em><em>,</em><em> </em><em>the</em><em> </em><em>total</em><em> </em><em>cost</em><em> </em><em>increases</em><em> </em><em>by</em><em> </em><em>$</em><em>1</em><em>0</em><em>5</em><em>.</em>

month 0: $0

month 1: $105

month 2: $210

month 3: $315

month 4: $420

month 5: $525

month 6: $630

<u>Club</u><u> </u><u>B</u>

<em>registration</em><em> </em><em>fee</em><em>:</em><em> </em><em>$</em><em>375</em>

<em>monthly</em><em> </em><em>fee</em><em>:</em><em> </em><em>$</em><em>8</em><em>0</em>

<em>Notice how</em><em> </em><em>Club</em><em> </em><em>B's</em><em> </em><em>total</em><em> </em><em>reaches</em><em> </em><em>Club</em><em> </em><em>A's</em><em> </em><em>total</em><em> </em><em>after</em><em> </em><em>2</em><em> </em><em>months</em><em>.</em>

month 0: $375

month 1: $455

month 2: $535

month 3: $615

month 4: $695

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.
