Answer:
The value of discountRate would be 0.01
Explanation:
double discountRate = 0.0;
int purchase = 1250;
if (purchase > 1000)
discountRate = .05;
if (purchase > 750)
discountRate = .03;
if (purchase < 2500)
discountRate = .01;
else discountRate = 0;
discountRate is declared as 0.0 then purchase is 1250. But the entire if statement is sequential, that is; all the if statement are executed.
first if-statement assign .05 to discountRate because purchase is greater than 1000.
Next if-statement re-assign .03 to discountRate because purchase is greater than 750.
The last if-statement re-assign .01 to dicountRate because purchase is less than 2500. Since this is the last if statement executed, the value of discountRate is .01
