Answer: the amount by which her lunch account would have been impacted is $45
Step-by-step explanation:
Each day Valerie charges her lunch account for her lunch. If the cost of lunch is $3 then, it means that Valerie charges the lunch account with $3 daily. It means that in x days, she would have charged her lunch account with 3×x = $3x
If she charged her account for a period of 15 days, it means that x = 15. Therefore, the amount by which her lunch account would have been impacted is 3×15 = $45
He needs to work 22 hours :)
(-x-2) (x-4) are the factor of this equation
Y = 3.5x
24= 3.5x
the train will be ride 6 times each day
and there are 7 days in a week
so multiply 6 and 7
=42
