Answer:
Step-by-step explanation:
1 inequality will model the number of hours he spends on the carvings per week and the other inequality will model the amount of money he will spend on materials per week.
He spends 3 hours on type X and 2 hours on type Y, so
3X + 2Y models the hours he spends on each. If he can spend up to 36 hours per week, the inequality sign is less than or equal to. Therefore, the inequality for the number of hours he can spend per week on type X and Y carvings is
3X + 2Y ≤ 36
Now for the money inequality.
He spends $4 for type X carvings and $5 for type Y carvings, so 4X + 5Y models that part of the inequality. If he can spend up to $100 per week, the inequality sign is less than or equal to here as well.
4X + 5Y ≤ 100
Those are the 2 inequalities that make up the system.
First. Find out what 25% of 500 is,then minus that from 500 five times.
It wont be worth anything because it will be $-125 in 5 years.
500-125-125-125-125-125= -125

Answer:
50 – (3x + 4y + 25)
Step-by-step explanation:
To see how much change she is gonna receive we need to find how much she spent on the items and add them all up:
The calculator was $25
The price of pens and notebooks are unknown so they are represented with x and y respectively.
With given information we can write the following equation to see the change she will receive:
50 – (3x + 4y + 25)
