Answer:Justin plans to spend $20 on sports cards. Regular cards cost $3.50 per pack and foil cards cost $4.50 per pack
number of packs of regular cards =r and the number of packs of foll cards = f
Cost of Regular card = 3.50
Cost of 'r' packs of regular card = 3.50r
Cost of Foil card = 4.50
Cost of 'f' packs of Foil card = 4.50f
Justin plans to spend $20 on sports cards so the sum of cost of regular and Foil cards should be less than or equal to 20
The inequality becomes
3.50r + 4.50f <= 20
Answer:
4x -51
Step-by-step explanation:
m(n(x)) = m(x - 10) = 4(x-10) - 11 = 4x -40 -11 = 4x -51
2500 * 0.9 = 2250
2250 * 0.9 = 2025 current stock
First we need to find the slope of the function
The slope of a function is equal to
So now we plug this into the equation and find the slope (M will represent the slope)
So the slope is -3/2
Now we can use point-slope form.
Point slope form is represented by
So when we plug in our values we get
So the equation is
Y = -3/2X-7/2
