Double check some of my work please?

1. 2(3) - 3(-2) = 0?

2. The piggy bank contained $25, and $1.50 is added each day. Would the expression of this be written as 25 + (1.50x)?

3. In the first set, the volleyball team made only 8 shots worth one point each. Would the expression for this just be 1 times 8?
