Answer:
The combined amount of raisins and oatmeal cookies sold are 80.
Step-by-step explanation:
At a bake sale there were 72 raisin cookies sold.
The ratio of raisin cookies to the oatmeal cookies sold was 9:1
Let the oatmeal cookies be = x
We get the following relation:
[tex]\frac{72}{x} =\frac{9}{1}[/tex]
=> [tex]9x=72[/tex]
x = 8
So there were 8 oatmeal cookies sold.
And the combined total is = [tex]72+8=80[/tex]
Hence, the combined amount of raisins and oatmeal cookies sold are 80.
