Dax IF, AND, BETWEEN DATES

[shophoney]

Hi, I'm trying to create a formula in DAX for:

If location ="9000"
And the date is between 4/1/18 and 6/30/18
Then take the SALES_GOALS[LY CORE]*1.5

=if(AND(SALES_GOALS[STORE]="9000",SALES_GOALS[LAST YEAR DATES (Month)]="apr"),SALES_GOALS[LY CORE]*1.5,SALES_GOALS[LY CORE]*1.1)

I've got it working if the month="Apr"

But need to have different sales goal increase for different months.

Can you suggest a formula?

Also would I be better to have a helper table that would contain the increases.

IE 9000, May, June x 1.5
Aug x 1.8....

Thanks
