<u>Corrected Question</u>
I am donating packages for Christmas drive. After the first week, I spent 126 to donate three children packages and 8 adult packages. After two weeks I spent 108 to donate six children packages and 4 adult packages. What is the price of each type of package
Answer:
Adult package costs $12
Child's package costs $10.
Step-by-step explanation:
Let the cost of a child's package =c
Let the cost of an adult package =a
<u>First Purchase</u>
Cost of three children packages and 8 adult package=$126
<u>Second purchase</u>
Cost of six children packages and 4 adult packages=$108
6c+4a=108
Multiply this equation by 2 to make the coefficient of a the same as the other equation
We solve the two resulting equations simultaneously
Subtract
-9c=-90
Divide both sides by -9
c=10
Substitute c=10 into 3c+8a=126 to solve for a
3(10)+8a=126
8a=126-30
8a=96
Divide both sides by 8
a=12
Therefore, an adult package costs $12 while a child's package costs $10.
Part A
There are 16 different outcomes because 4*4 = 16. There are four letters so that's why we multiply those two '4' terms. This is only if we allow repeat letters. If we spun 3 times, then we would have three copies of '4' multiplied together. This idea can be extended on forever.
====================================================
Part B
The 16 different outcomes are:
{H,H} {H,P} {H,E} {H,O} {P,H} {P,P} {P,E} {P,O} {E,H} {E,P} {E,E} {E,O} {O,H} {O,P} {O,E} {O,O}
Each different outcome is in its own set of curly braces.

Answer:
y=1/3x-2
Step-by-step explanation:
i think its right
2x + 2(x-90) = 3480
2x + 2x - 180 = 3480
4x = 3660
x = 915 mph Plane 1 westbound
915-90 = 825 mph plane 2 eastbound
