Question 97448
Let x=oz of pure gold
amount of alloy=5*.01= .05
amount of pure gold=1.00*x= x
amount of pure gold + alloy= .06(5+x)=.3+.06x
.05+x=.3+.06x
.94x=.25
x=.266 oz of pure gold
Check:
.266+5=5.266 total oz
.05+.266=.316 oz of pure gold
.316/5.266=.06 or 6%
You were right.
It was more difficult than usual to chek this one.
Keep up the good work!
