Zach needs a new pair of Nike Air Max. The pair that he wants regularly sells for $129. If they are on sale for 24% off, how much will he pay in total if sales tax is 6.4%?

$104.31

Step-by-step explanation:

First we need to find what the price is with 24% off. To find that, we convert 24% to a decimal and we get .24

129 • .24= 30.96

30.96 is how much is off the original price. So we subtract.

129-30.96= 98.04

To find the sales tax, we do the same.

98.04 • .064= 6.27456

(6.4% is .064 as a decimal)

98.04+6.27456= 104.31456

We add because the sales tax is going to be added to the price. Since 104.31456 isn’t a real thing money wise, we round it up to 104.31.

Thus, 104.31 is the price of the shoes.

step-by-step explanation:

hello and welcome!

so, when we see the words "proportional" along with a table, we need to know that we're looking numbers that divide by the same thing.

looking at this table, we simply have to do a trial and error, and divide to see which numbers have the same quotient. if you look at choice a & c, they both have equal quotients for three of the numbers, with one exception, so those can't be the answer. looking at b, there is no similarity, so that can't be it. then, we see d; if you divide all the numbers in the table, you'll see that they all divide by two, which is a proportional relationship, and our answer!

also, always remember that the x will always be the number that goes into y, and somewhere behind this table, is a formula. for this specific table, the formula would be:

since our x-value is being divided by two to get the y-value. and if they were to ask for more numbers in the series, this is the formula you would use to find them.
