If 1/8 of my money is $80. What is 50 % of my money

$320

Step-by-step explanation:

An easy way to solve this problem is to undo the operations, Find the total amount of money, and then find half of the amount. Since (80) is () the total amount of money, one has to multiply (80) by (8) to find the total amount of money.

(80) * (8)

= 640

Now one is asked to find (50%) of the money. It is known that (50%) is equivalent to (0.5), therefore multiply (640) by (0.5) to find how much (50%) of the money is.

(640) * (0.5)

= 320

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5
