P = original price of the item P'= new price after discounted P'= [Px(1-50%)]x(1-50%) P'= 0.5Px 0.5 P'= 0.25P P' is 25% of original price or discounted by 75% less

Q1 We can get a table : Balance 1040 995.8 951.6 907.4 month(m) 0 1 2 3 We get the function: Tm = 1040-44.2m Q2 1040 > 44.2m 23.5 > m It can pay for 23 months without deposting any more money.

let the first no. be X let the second no. be X+1 (3/4)X= X+1+5 Then solve for X to get the answer

Let T hour be the time when Trigger & Silver travelled and 3 km apart. 30T - 25T = 3km T=3/5 hour T= 36 minutes

Let Matty's principle be $P Px 8.2%/12= 400 Then solve for P

I agree with Steve this equation is impossible to solve
