The price to cover ornaments is a fixed amount plus a percentage of the value of the ornaments.

It costs $32 to insure $1000 worth of jewellery or $44.50 to insure $3500 worth of jewellery.

What is the fixed amount to insure jewellery?

A. $27.00

B. $31.25

C. $44.65

D. $58.82

This is what I got told to you, but like y do u have to subtract, I get the first equation, I don't get the second, and It still has to be solved. I really don't understand, please help

F = fixed amount

P = percentage

F + P(1000) = 32

-[f + p(3500) = 44.50]

(1) F + 1000P = 32

(2) F + 3500P = 44.50

you have to solve these 2 equations simultaneously

By elimination method, to eliminate F, multiply one of the equations by -1

-1(F + 1000P = 32)= -F - 1000P = -32

Now ADD these two equations together

-F - 1000P = -32

F + 3500P = 44.50

0 + 2500P = 12.5

2500P = 12.5

P = .005

substitute P = .005 in one of the equations to find F

F + 1000P = 32

F + 1000(.005) = 32

F + 5 = 32

F = 27

What is the fixed amount to insure jewellery?

A. $27
