UR Safe Systems installs home security systems. Two of its systems, the ICU $100$ and the ICU $900,$ have these

characteristics:

The ICU $100$ sells for $$970$ installed, and the ICU $900$ sells for $$1,680$ installed.

Required:

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

UR Safe's management believes that it must drop the price on the ICU $100$ to $$910$ and on the ICU $900$ to $$1,550$ 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.

$($For all requirements, round your percentage answers to $2$ decimal places $($i$.$e$.1234=12\mathrm{.}34\%)$ and other answers to the nearest

whole dollar amount.$)$
