Answer:
$ 75.
Step-by-step explanation:
From the information above,
List price of model II = $240
Sale price of the clearance sale is 1/4 off the list price of Model II microwave oven and additional 1/5 of the sale price for oven that are scratched and dented.
Therefore,
Let the sale price be X,
= (1/4)*(list price) + (1/5)*X
X = (1/4)*(240) + (1/5)*X
X = 60 + (1/5)X
Solving for X,
X - (1/5)X = 60
(4/5)X = 60
X = (60*5)/4
= $75.
There are no numbers without decimals which multiply to 78 and add up to 17.
314,852
I mean this one is really simple, it just seems hard. So all u have to do is this:
308,328+6,524=314,852
Now subtract to double check
314,852-308,328=6,524.
And yep it’s correct.
I hope this helped, please give brainliest if it helped
Catherine could take the original price of $144.97 and multiply it by .09 (9%). This would equal a sales tax of $13.073 which could be rounded to $13.01. Then add the original price of $144.97 to the tax of $13.01 to get a total of $157.98.
