abercrombie & Fitch is having a sale. The sign posted in the store says, "everything is marked down 65%." Scott buys a jacke

nikdorinn [45]

a) We have that the discount is 65 %

Scott buys a jacket for $150

First, we will calculate the discount

$150\times\frac{65}{100}=97.5$

then we need to subtract the quantity calculated above from the original price

$150-97.5=52.5$

After the markdown Scott paid $52.5

In order to know the taxes first, we need to calculate the 5% of $52.5

$52.5\times\frac{5}{100}=2.625$

then we will sum the 5% plus the price after the markdown

$52.5+2.625=55.125$

The total cost of the jacket is $55.125

I have 28 cubes. how many ten and ones i can make?

Alexandra [31]

2 tens, and 8 ones. I say this because 20 = 10 + 10 so, two tens. 8= 1+1+1+1+1+1+1+1 so, eight ones.
