Have you considered doing it "from other end"?

A 15% discount means you <u>pay</u> 85% of the selling price.
. . 85% of $5900 .= .$5015

A 10% discount means you <u>pay</u> 90% of the price.
. . 90% of $5015 .= .$4513.50

A 4% discount means you <u>pay</u> 96% of the price.
. . 94% of $4513.50 .= .$4332.96 .<--- the amount you <u>pay</u>

In fact, it can be done in one step: .0.85 × 0.90 × 0.94 × $5900 .= .$4332.96

[Try that the next time you have consecutive discounts.]
