Answer:
The answer is A.
Step-by-step explanation:
So we have the two equations:
To make a substitution of the second equation into the first equation, we need to isolate the <em>y </em>variable in the second equation. Thus:
Now, we can substitute this into the first equation. Therefore:
Answer:
Jena spends $ 733. 33 on her rent and groceries altogether per month.
Step-by-step explanation:
Jena's total income in a month= $1600
Here , expenditure on rent = (1/3) of her income
So, now one- third of her income $1600 is
=
or, (1/3) of her salary is $533. 33
Hence, Jena spends $ 533. 33 on her rent monthly.
Now, her expenditure on groceries = (1/8) of her income
So, now one- eighth of her income $1600 is
=
or, (1/8) of her salary is $ 200.
Jena spends $ 200. on her groceries monthly.
So, Total expenditure = Expenditure on rent + Expenditure on groceries
= $533. 33 + $200 = $733.33
Hence, Jena spends $ 733. 33 on her rent and groceries altogether per month.
