To calculate P(at least one valve opens), we can find 1 - p(no valves open).
This is equal to 1 - (0.05)^5, or 0.9999996875.
P(at least one valve fails to open) is equal to 1 - p(all valves open and none fail). This is 1 - (0.95)^5, or 0.2262190625.

Answer:
A. $11.75
B. $1.75x + $1.00y = c (cost)
Step-by-step explanation:
A. Because apples cost $1.75 each you could multiply the amount of apples you intent to buy by $1.75 which in this case the amount of apples wanted is 3. $1.75 x 5 = $8.75. You would do the same thing for the peaches except the amount per peach is different. $1.00 x 3 = $3. Then you would add the two amounts together to get the amount Brooklyn and her friend would have to pay. $8.75 + $3 = 11.75
B. Because you multiply the amount of items you intend to get by the cost per item the equation you would follow if the amount of items changed would be. $1.75x + $1.00y = c (cost)
