Answer:
The answer is 7 she Can Buy 7 packages of cookies.
Step-by-step explanation:
1. 15-5.50=9.50
2.9.50-7.75=1.75
3. 1.75-0.25*7=0
She wouldn't have any money left over to buy it
-k + 0.03 + 1.01k = -2.45 - 1.81k
Multiplying through by 100, we have
-100k + 3 + 101k = -245 - 181k
The slope is -1/2. I know this because slope intercept of a line is y = mx + b. In the equation, y = -1/2 + 1/4, the slope is -1/2 and the y intercept is 1/4.
m stands for slope
b stands for y intercept
