You should start with an equation.
The 'x' represents the week.
so now, we have to subtract 125 from the total amount which is 245.
now we have
to find 'x', we must divide 15 on each side
we are now left with
that means Sierra will have 8 weeks until she has enough money to buy the bike
Answer:
2nd option
Step-by-step explanation:
makes most sense
Answer:
C. y +3 = x +3
Step-by-step explanation:
We need to find in below option x has direct variation with y.
We solve for each;
A. 
From above equation we can state that 2 times y is equal to 7 less than 3 times of x.
Hence it doesn't represent direct variation.
B. 
Solving above expression we get;
From above equation we can state that y is equal to 10 more than x.
Hence it doesn't represent direct variation.
C. 
Solving above expression we get;
From above equation we can state that y is equal to x.
Hence it represent direct variation.
D. 
Solving above expression we get;
From above equation we can state that 4 times y is equal to 2 less than 4 times of x.
Hence it doesn't represent direct variation.
Hence the Answer which represent direct variation of x and y is,
C.
