Trey buys his favorite fishing lure in quantity. The total amount, y, Trey pays for his purchase is proportional to the number,
x, of favorite lures he buys. Each lure's price is $1.25. Which equation represents the total amount of Trey's purchase of his favorite lure?
2 answers:
Answer:
y = 1.25x
y (total amount Trey pays) is the dependent variable and x (number of lures purchase) is the independent variable
y = kx → y = 1.25x
Answer:
y(x) = ($1.25/lure)x
Step-by-step explanation:
Let the total amount be y(x) (which says, "y is a function of x"). Then
y(x) = ($1.25/lure)x.
Checking this out, we see that 1 lure will cost $1.25, 2 will cost $2.50, and so on. x represents the number of lures purchased.

for taxes
30%of y
30/100×y=3y/10
=0.3y
freight charges =65
total =520
0.3y+65=520
0.3y=520-65
0.3y=455
y=455/0.3
y=$1516.7
y≈$1517
