Question

I ain't big sale there is 72 raisin cookies sold If the ratio of Raisin Cookies sold to oatmeal cookies was 9:1 why was the combined amount of raising an oatmeal cookie sold

Answer 1

Let x be the combined amount of raising and oatmeal cookies sold:

Since, the amount of raisin cookies sold= 72

And the ratio of raisin cookies to oatmeal cookies is 9:1

Then,

`\begin{gathered} (9)/(1+9)\cdot x=72 \\ (9)/(10)\cdot x=72 \\ x=(72\cdot10)/(9) \\ x=(720)/(9)=80 \end{gathered}`

The combined amount of raising and oatmeal cookies sold were 80
