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
