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!!!
🤔😵🥱😴🤤😮😑😞😴
The order I follow everyday😁
sorry not trying to be rude
since there is only one necklace, and any number of beads,
clearly, the necklace costs 9.50, and each bead costs 1.75
A. To determine Olivia's total cost if she buys 15 beads, we can substitute x = 15 into the equation f(x) = 1.75x + 9.50 and evaluate it.
Step 1: Substitute x = 15 into the equation:
f(15) = 1.75(15) + 9.50
Step 2: Perform the multiplication:
f(15) = 26.25 + 9.50
Step 3: Add the two values together:
f(15) = 35.75
Therefore, Olivia's total cost if she buys 15 beads is $35.75.
To determine Olivia's total cost if she buys 40 beads, we can follow the same steps.
Step 1: Substitute x = 40 into the equation:
f(40) = 1.75(40) + 9.50
Step 2: Perform the multiplication:
f(40) = 70.00 + 9.50
Step 3: Add the two values together:
f(40) = 79.50
Therefore, Olivia's total cost if she buys 40 beads is $79.50.
B. In the equation f(x) = 1.75x + 9.50, the 1.75 represents the cost of each individual bead. The coefficient 1.75 indicates that each bead costs $1.75.
C. In the equation f(x) = 1.75x + 9.50, the 9.50 represents Olivia's initial cost or fixed cost for purchasing the rose gold chain. It indicates that Olivia has to spend $9.50 regardless of the number of beads she buys. It might account for the material or manufacturing costs of the chain itself.
