Work backwards.
After she put half of what she had left in, she had 17.76.
Multiply by 2:
17.76 * 2 = 35.52
Add 25:
35.52 + 25 = 60.52
Add 14.48:
75
So she received $75 on her birthday.
Let the price of 1 shirt be represented by = s
A pair of pants costs twice as much as a shirt, then the cost of pants is = 2s
The total cost of 1 pair of pants and 1 shirt is $18 , means : 
Solving this we get,
So, the price of 1 shirt is $6 and price of 1 pair of pants is = 2s = 2*6 = $12.
I got this answer by first using the slope formula, which would result into 
for which the answer would be - ⅔ Then, the y-intercept could be found easily, since you already have it., which is (0,4). Since the format for all linear equations are y=mx+b , in which b means the y-intercept and m means the slope. So then, if you substitute - ⅔ for m and 4 for b , you would get
Answer:
The answer is option C
Step-by-step explanation:
104
E 6
x = 1
Write the number as a product with the factor 1
104
E 6 × 1
n = 1
Rewrite the sum
That's
104
6 × E 1
n = 1
Find the sum of n terms of 1 using the formula
n
E 1
k= 1
Which is
6(104) = 624
Hope this helps you
