Answer:
13.75
Step-by-step explanation:
First you know there are 5 students and 5 teachers, for each student it costs 6.25 and for every teacher it cost 1.50. So 5 teachers x 1.50= 7.5. 5 students x 1.25 =6.25. 7.5 +6.25= 13.75
Try to use the total which is 650 - 247
by that will give you the answer
Since the expression 7h + 1.50d can be used to find the total earnings. We just need to substitute the given data to the expression to solve the problem.
7(15) + 1.50(8)
105 + 12 = 117
Colton's total earnings after working 15 hours and making 8 deliveries is 117 dollars.
7x-y=14 :add 'y' to both sides
7x=14+y :divide both sides by 7
x=(14+y)/7 or x=2+(y/7)
Answer:
A. $0.5
Step-by-step explanation:
In this question half of the time your winning is 2 dollars and also the other half of the time your loss is one dollar
The expectation is that after you must have had 2 rolls you would get 2 dollars once and also you are going to lose 1 dollar once. So what you won overall would be 1 dollar.
So the correct answer would be gotten from $1/2rolls
= $0.50
