a department store is having a sale where all items are 45% off their original prices (meaning the buyer gets to decrease the price by 45%). the store must charge an 8% sales tax on the final cost of any item. parker wants to buy a jacket that was originally $240

$116.64

Step-by-step explanation:

I'm guessing you're asking what the final price of the jacket is.

1. 45% of $240 is $108

2. 8% of $108 is $8.64

3. $240 + $8.64 = $116.64

Hope this helped. :)

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
