Olivia bought a rose gold chain. Wants to buy decorate of beads to put on the chain. The equation below can be used to determine y, Livius total cost in dollars to buy a rose gold chain and x decorate beads. f(x)=1.75x+9.50
A. use the equation to determine Olivia‘s total cost if she buys 15 beads and 40 beads you must show all your work and explain your steps
B. what does the 1.75 in the equation represent explain your reasoning
C. what does the 9.50 in the equation represent explain your reasoning

Help please I’ve been trying to figure this out for 20 minutes!!!

step-by-step explanation:

1. practice, practice & more practice

2. review errors

3. master the key concepts

do not try to memorise the processes.

4. understand your doubts.

5. create a distraction free study environment

6. create a mathematical dictionary

7. apply maths to real world problems.

25% is the answer

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
