Answer:
$372
Step-by-step explanation:
If after 4 years, you had $489 and after 6 years, you had $567 on your account.
We first determine the slope of the points (4,489) and (6,567).
Using the slope-Intercept form, y=mx+c and the first value $489
y=mx+c
489=39(4)+c
c=489-156=333
The equation of the line is:
y=39x+333
The Initial Deposit,y at x=1
y=39(1)+333
Initial Deposit =$372

Answer:
The answer is below
Step-by-step explanation:
Let x represent the number of single cone ice cream and let y represent the number of double cone ice cream.
Since the vendor stocks a maximum of 70 single cones and a maximum of 45 double cones. hence:
0 < x ≤ 70, 0 < y ≤ 45 (1)
The vendor expects to sell no more than 50 ice creams, hence:
x + y ≤ 50
Plotting the constraint using geogebra online graphing tool, we can see that the solution to the problem is at (5, 45)
Since the vendor sells single-cone ice-creams for $3 and double-cone ice-creams for $4.50, hence:
Revenue = 3x + 4.5y
At the point (5, 45), the revenue is:
Revenue = 3(5) + 4.5(45) = $217.5
