Dear Joshua Harnwell,Very good work!Should the calculation of Q19 be 1/2 pi ab - 5 x 2 where a is 7 and b is 8? This will come to answer A.Happy New Year!
Hey!Shouldn't question 2 be (c) ? Because it's already including GST?And you just have to MINUS the amount.Let me know if I'm right or wrong.I'm just revising for the hsc.Thank you :)

No, the formula to get amount exc. gst = amount inc. gst / 1.1Formula to get gst amt = amt inc. gst / 11
