Let x=number of hamburgers sold and y=number of hot dogs sold.
Step 1)
cost of burgers X # of burgers + cost of hotdogs X # of hotdogs=$ collected 1.5x + 1.25y=105.5
step 2)
# of burgers sold + number of hot dogs sold = total number of items sold
x + y = 78
step 3) solve for y in the second equation
y = 78 - x
step 4) substitute y = 78 - x in the first equation for the value of y and solve for x
1.5x + 1.25(78 - x)=105.50
1.5 x + 97.5 - 1.25x=105.50
.25x = 8
x = 32
step 5) plug in our value for x in the second equation and solve for y
x+y=78
32+y=78
y=46
answer 32 hamburgers and 46 hot dogs
In the equation of a circle in the form (x-h)^2 + (y-k)^2 = r^2, (h,k) is the center and r is the radius.
So, the center of the circle is at (-4,2) with radius 6 units.
Answer:
14.4 acres for corn (if you need to round, it's 14 acres.)
Step-by-step explanation:
40% = 19.2 acres
20% = 9.6 acres
10% = 4.8 acres
40 + 20 + 10 = 70
100-70 = 30
30% = 14.4 acres
6 x 2 + 4 x 3 = 12 + 12 = 24
