Ashley has x dollars. She spends $23.50 on a birthday gift. She decides to keep 0.4 of what she has left, which is $13.80. How many dollars did Ashley have originally? Write both the equation you used and the answer.

She has $58 initially

The equation is;

0.4(y-23.5) = 13.8

where y is the original money she has

Step-by-step explanation:

Let the amount she has originally be $y

she spends $23.50 on a birthday gift

what is left will be;

(y- 23.50)

She decides to keep 0.4 of this and this is equal to 13.8

Thus;

0.4(y-23.5) = 13.8

y- 23.5 = 13.8/0.4

y- 23.5 = 34.5

y = 34.5 + 23.5

y = $58

x= -3

step-by-step explanation:

step 1: simplify brackets

4 - x - 1 = 6

step 2: simpilfy

3 - x = 6

step 3: subtract 3 from both sides

-x = 6 - 3

step 4: simpilfy 6 - 3

-x = 3

step 5: multiply both sides by -1

x = -3

the answer is a

step-by-step explanation:

because if you put 1 in to the square root of x it equals 300.
