470 = 8.75(46 - c) + 11c
470 = 402.5 - 8.75c + 11c
67.5 = 2.25c
30 = c
If c = 30 and Soren worked 30 hours in the office, earning $11 per hour, he earns $330 from his office job. 46 - 30 = 16, which should be the remaining amount of hours Soren worked. 16 * 8.75 = 140. He earned $140 from his cashier job. $330 + $140 = $470.
The correct formula to solve this problem is A. 11c + 8.75(46 - c) = 470

Answer:
The school baseball team sold 270 tickets
Step-by-step explanation:
Step 1
Identify the total amount of tickets sold by each player;
1 player=1 book of tickets
But 1 book=10 tickets
Step 2
Express the total cost of ticket sales per book as follows;
total cost=cost per ticket×number of tickets per book
where;
cost per ticket=$3
number of tickets per book=10
replacing;
total cost=(3×10)=$30
Step 3
Using the expression below, solve for the number of tickets sold
Total amount raised=price per ticket×number of tickets sold
where;
total amount raised=$810
price per ticket=$3
number of tickets sold=n
replacing;
810=3×n
3 n=810
n=810/3=270
n=270
The school baseball team sold 270 tickets
Nathan has an infection and he needs to be treated with penicillin
But there’s a 75% probability of him being allergic to penicillin
And to test if the skin reacts to penicillin, the test is 98% accuracy
So even if he has the allergy the test is only 98% accurate of identifying the allergy
Therefore we are asked to find the probability of both these events happening
Event 1 and event 2 both should happen then. When the ‘and’ function is used in probabilities then the probabilities of both events happening should be multiplied
Therefore probability that Nathan has the allergy and test predicts it is
= 75% x 98% = 0.735
The answer is D. 0.735
