$1.$ What are the current gross profit margin percentages on both systems?

$2.$ UR Safe$$s management believes that it must drop the price on the ICU $100$ to $$750$ and on the ICU $900$ to $$1,390$ to remain competitive in the market. Recalculate gross profit margin percentages for both products at these price levels and then compute the target cost needed for each product to maintain the current gross profit margin percentages.
