Mrs gopal bought 4 similar watches and 5 similar braclets and had $201 left.of she had bought 8 such watches and 4 such braclets,she would have spent all the money she had.each braclet costs $117 more than each watch.how much money did mrs gopal have at first?

answer with a clearly drawn model and math statements that are easy to understand.

M=total money she had at first.
w=cost of a watch
b=cost of a bracelet

m=4w+5b+201(1)
m=8w+4b(2)
b=w+117(3)

(1)-(2)⇒ 0= -4w+b+201=-4w+(w+117)+201[using (3)]
                =-3w+117+201=-3w+318
so, w=318/3=106
       b=w+117=106+117=223[using(3)]
from (2),
          m=8(106)+4(223)=1740 thats the answer
       

C

Step-by-step explanation:

The percentage is calculated as

% = × 100%

Total number of cars = 28 + 16 + 24 = 68

number of blue cars = 28, then

% blue = × 100% = 41% ( to the nearest percent )
