Katie bought 4 sweaters that each cost the same amount and 1 skirt that cost 20$. the items she bought cost a total of 160$ before tax was added. what was the cost of each sweater?

The cost of each sweater was $35

Step-by-step explanation:

To find this, first find out the cost of all the sweaters added together. We can get this by subtracting the cost of the skit from the total.

$160 - $20 = $140

Now to find the individual cost, divide the cost of all the sweaters by the number of sweaters.

$140/4 = $35

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.

answer: c

because if you look at the chart you can see a pattern and compare it to the question he simplify out your

but i think the formula is f(x)=6x
