Answer:
cost for adults: 2×$12.50
cost for children: 3×$8.00
total cost: 2×$12.50 +3×$8.00
$49.00
Step-by-step explanation:
Assuming I, my brother, and my sister qualify for children's tickets, we have ...
cost for adults: 2×$12.50
cost for children: 3×$8.00
total cost: 2×$12.50 +3×$8.00
Evaluation:
$25.00 +24.00 = $49.00 . . . . . . . multiplication is performed first
Answer:
$ 10.69
Step-by-step explanation:
225 is 2.25 times the 100 pencils. ( 225/100) So all you have to do is multiply 2.25 the price ($4.75) and you get 10.6875, money can only go to the tenth place so you round it to $10.69

The solution to the system of linear equations is where the two lines intersect.
Look for the point where the two lines intersect. The x-value is 2 1/2, and the y-value is -4.
The answer is C.
Suppose the length of the card board was x cm by x cm
After squares of 4cm was cut from the corner, the dimension for the box will be:
length=(x-8) cm
width=(x-8) cm
height=4 cm
thus the volume will be:
V=length*width*height
V=4×(x-8)×(x-8)=144
x²-16x+64=36
this can be simplified to form a quadratic equation given by:
x²-16x+28=0
solving the quadratic equation we get:
x=2 or x=14
Thus we conclude that the original dimensions was:
length=14 cm ; width=14 cm
