Answer:
So a bag of chip costs $2.39
Step-by-step explanation:
Let x = cost of a bag of chip
Let y = cost of a box of pretzel
Micheal buys two bags of chips and three boxes of pretzels for $5.13
This means
2x + 3y = 5.13 - - - - - - - - - -1
He then buys another bag of chips and 2 boxes of pretzels for $3.09
This means
x + 2y = 3.09 - - - - - - - - - - - -2
Solving equation 1 and equation 2 simultaneously and using the elimination method,
Multiply equation 1 by 1 and equation 2 by 2
2x + 3y = 5.13
2x + 6y = 6.18
Subtracting,
-3y = -1.05
y = -1.05/-3= $0.35
Put y= 0.35 in equation, x + 2y = 3.09
x + 2(0.35)= 3.09
x + 0.7= 3.09
x = 3.09-0.7 = $ 2.39
So a bag of chip costs $2.39
Answer:
B
Step-by-step explanation: edge
Based on the total of intervals vs the number of intervals Amy attended her CA percentage is 75%
<h3>What is the CA percentage?</h3>
The CA percentage measures the commitment of an employee to be logged in during the intervals that were assigned to him/her to work.
In this way, the CA percentage is equal to 100% if the employee worked as scheduled. Moreover, this percentage can be affected by factors such as:
- Technical issues.
- Human errors.
In the case of Amy, there is a total of 12 intervals and it is known:
- She had a technical issue that prevented her from working, but this was reported so it is unlikely this is considered in her CA.
- She missed three intervals because she looked at her schedule wrong.
Based on this information, let's calculate her CA:
- 12 intervals = 100%
- 9 intervals = x
- x = 9 x 100 / 12
- x = 900 / 12
- x = 75%

-4x+29? I think that's what you're asking.
