Let's calculate Evan's expenses and see how much money he has left after each purchase.

Evan buys a new bicycle for $396.95.

Money spent so far: $396.95

Money remaining: $580 - $396.95 = $183.05

Evan buys 4 bicycle reflectors for $7.40 each.

Cost of 4 reflectors: 4 x $7.40 = $29.60

Money spent so far: $396.95 + $29.60 = $426.55

Money remaining: $580 - $426.55 = $153.45

Evan buys a pair of bike gloves for $22.94.

Money spent so far: $426.55 + $22.94 = $449.49

Money remaining: $580 - $449.49 = $130.51

Now, Evan plans to spend some or all of the money he has left to buy new biking outfits for $42.10 each. To calculate how many biking outfits he can buy with the remaining money:

Number of biking outfits = Money remaining / Price per biking outfit

Number of biking outfits = $130.51 / $42.10 ≈ 3.10 (rounded to the nearest whole number)

Since Evan can't buy a fraction of a biking outfit, he can buy 3 biking outfits for $42.10 each.

Total spent:

Bicycle: $396.95

Reflectors: $29.60

Gloves: $22.94

Biking outfits (3 x $42.10): $126.30

Total spent = $396.95 + $29.60 + $22.94 + $126.30 = $575.79

Evan spent a total of $575.79, and he has $580 initially, so his remaining balance is:

Initial balance - Total spent = $580 - $575.79 = $4.21

Evan has $4.21 left after all his purchases.
