Iris paid $120.00 for a winter coat. She saved 25% off the original price.
What was the original price of the coat?

120/100=1% of price after some discount

1%=1,2

1,2×125=150 it is originall price

$160, or answer A

Step-by-step explanation:

If 120 is 25% of the original, or 0.25 of the original(We will call it x), then 120 is 0.75x.

Form an equation like this:  0.75x=120

Turn this into fractions:  3/4x=120/1.

Divide by 3/4 on both sides.

x = 120/1 * 4/3

Simplify to get: 40/1 * 4/1

Multiply to get: 160

0

step-by-step explanation:

you can not divide by 0 so 4 ÷ 0 would be 0

0 × 9999 =0

geometric series converge the common ratio r has magnitude less than one.

which is equivalent to

for the example we need

|2-x| < 1

-1 < 2-x   and 2-x < 1

x < 3 and x > 1

we can write that

answer: 1 < x < 3

1a. common ratio r=250/25=10 > 1     diverges

1b.   r=50/100=1/2 converges

when these converge they converge to

where a is the first term.

answer: 200

1c. r=-1   so it's not the case that |r| < 1.     diverges

2a. x is the common ratio so we converge when |x|< 1

2b.   r=-10x / -2 = 5x.

we converge when

|5x| < 1

|x| < 1/5

2c.   r=3-2x

-1 < 3-2x and 3-2x < 1

-4 < -2x and 2 < 2x

x < 2 and 1 < x

1 < x < 2

2d. [/tex] r=-48x^3/12 = 4x^3[/tex]

|4x^3| < 1

|x^3| < \frac 1 4

|x| < 4^{-1/3}
