a)3y+x=3w 10 variant 11 Q16 too
a)3y+x=3
3y=-x+3
y=-x/3+3/3
y=-x/3 +1
m= -1/3

let c =cost a= weight of coffeethe price of coffee has increased by 25% what percentage of coffee consumption is to be decreased so that there would be no increase in the expenditure for a household???? how to do thisZ???
l
let c =cost a= weight of coffee
ca=125/100c *(xa)
ca=1.25c*(xa)
ca/1.25c=xa
a/1.25=xa
a/1.25 * 1/a=x
1/1.25=x
%age decrease= 1-1/1.25
=20%
