A family ordered some c andy bars and bags of chips for snacking. The number of candy bars was twice as much as the number of bags of chips. If the family spent a total of $5.50, how many bags of chips did the family buy? I know the first equation is c=2b c for candy and b for bags of chips
PLEASE HELP!!

option (a)

step-by-step explanation:

step 1:   take 2 number whose product equal to 25..

and sum of those two number are -10

step: 2 for example here if we take 5,5 are the number,,

5*5=25

and

5+5=10

but we need -10

so if we take   -5,-5

so -5*-5=25

and -5+(-5)=-10

s0

come the equation

replace -10x by these number

like -5x -5x+25

take common

x(x-5)-5(x-5)=0

(x-5)(x-5)=0

i think you forgot some signs inbetween? if so comment and i'll try to
