Answer:
$54.40
Step-by-step explanation:
First, find the new price after the 20% markdown:
80(0.8)
= 64
Then, find the price with the 15% markdown:
64(0.85)
= 54.4
So, the new price of the coat is $54.40
The correct answer choice is 4
Answer:
2
Step-by-step explanation:
$44 / 22 = 2
So first multiply the whole numbers.
6x2=12
Now multiply 6 and 7. When multiplying a fraction like this, do the numerator ONLY. So it ends up being 42/10. That can be turned to a mixed number. To do that, find out how many times 10 can go into 42. The highest whole number is 4.
10x4=40 and there's 2 left over. So make it 2/10 which can be simplified to 1/5
Now add.
12+4=16+1/5= 16 1/5
