Let us assume the number of times Bill saved $75 from his paycheck = x
Let us assume he number of times Bill saved $150 from his paycheck = y
Since he saved 75$ or 150$ for the 8 paychecks.
So, x+y=8
y=8-x (Equation 1)
Since Bill saved $825 from his last 8 paychecks using $75 or $150.
So, 75x+150y=825 (Equation 2)
Substituting the value of 'y' from equation 1 in equation 2,
x = 5
Therefore, Bill saved $75, 5 times from his paycheck.

Answer:
165 ways to choose the paintings
Step-by-step explanation:
This is clearly a Combination problem since we are selecting a few items from a group of items and the order in which we chosen the items does not matter.
The number of possible ways to choose the paintings is;
11C3 = C(11,3) = 165
C denotes the combination function. The above can be read as 11 choose 3 . The above can simply be evaluated using any modern calculator.
Answer:
24% probability that both fund A and fund B will rise in price
Step-by-step explanation:
We have these following probabilities:
40% probability that fund A will rise in price.
If fund B rises in price, 60% probability that fund B does.
What is the probability that both fund A and fund B will rise in price
40% of A, and if A rises, 60% is B. Since the only outcome that interests us is both rising in price, we multiply these probabilities
24% probability that both fund A and fund B will rise in price
Answer:
$7.5
Step-by-step explanation:
Let
Quantity of stickers=x
Price of stickers=y
5 stickers cost $3
12 stickers cost $y
x/y = x/y
5/3 = 12/y
Cross product
5y=12*3
5y=36
Divide both sides by 5
5y/5 = 36/5
y=7.5
12 stickers= $7.5
Therefore, the price of 12 stickers= $7.5
