Answer:
a. We spent all together 40.2+24.5+37.8=$102.50.
b. We saved 19.8+10.5+7.2=$37.50
c. 
Step-by-step explanation:
To find the amount we spend, we multiply the original price by the decimal conversion of each fraction. Then we add the amounts together.
- Sneakers cost $60 and you bought them at 2/3=0.6666....
60(0.67)=$40.20 and saved $19.80
- Sweater costs $35 and you bought it at 7/10=0.7
35(0.7)=$24.50 and saved $10.50
- A jacket costs $45 and you bought it at 5/6=0.8333...
45(0.84)=$37.80 and saved $7.20
We spent all together 40.2+24.5+37.8=$102.50.
We saved 19.8+10.5+7.2=$37.50
We could of spent paying regular price 60+35+45=$140. To find the fraction we place the total we actually paid over the total regular price.

X= -3/2y+3/17z
y=-2/3x+2/17z
z=-17/3x+17/2y
A parent function is the function from which all similar functions can be derived.
The given function f(x) = - 3x + 2 is a linear function, so its parent function must have to be a linear function.
The parent linear function is f(x) = x
Note that you can derive the above function from x by first multiplying it with -3 and then adding 2.
So the correct option is option C
