X = adults
Y = child
X+y=168
X=168-y
$10x + $7y = $1446
10(168-y) + 7y = 1446
1680 - 10y + 7y = 1446
-3 y = -234
Y = 78
X = 168-78
X = 90
$10*90 + $7*78 =
$900 + $546 = $1446

Answer:
P( sum is prime )= 73/216
Step-by-step explanation:
The minimum value of the sum will be 3 and maximum value will be 18. So the prime numbers in this range are 3 , 5, 7, 11, 13, 17.
P(sum=3)=1/216, P(sum=5)=6/216, P(sum=7)=15/216, P(sum=11)=27/216, P(sum=13)=21/216, P(sum=17)=3/216.
The final probability will be sum of the above given probabilities.
Hence P( sum is prime )= 73/216
1 gallon is 8 pints....so 1/2 gallon = 4 pints
she fills a 1 pt thermos with milk each day......how many times will she be able to fill her thermos with 1/2 gallon (or 4 pints) of milk ?
if she fills a 1 pint thermos each day....and she has 4 pints of milk, then she will be able to fill her thermos 4 times <===
