You run 1/2 mile on Sunday. On each day after the weekend, you run 1.5 times as far as you did the day before.
a) How far do you run Monday?
b) Write and evaluate an expression to find the distance you un 5 days after Sunday (Friday). Round to the nearest tenth of a mile.
If you can help me than please do! 
I would like you to tell me how you did it though. Thanks!
basically
monday $${\mathtt{0.5}}{\mathtt{\,\times\,}}{\mathtt{1.5}} = {\frac{{\mathtt{3}}}{{\mathtt{4}}}} = {\mathtt{0.75}}$$
then
tuesday $${\mathtt{0.75}}{\mathtt{\,\times\,}}{\mathtt{1.5}} = {\frac{{\mathtt{9}}}{{\mathtt{8}}}} = {\mathtt{1.125}}$$
and
wednesday $${\mathtt{1.125}}{\mathtt{\,\times\,}}{\mathtt{1.5}} = {\frac{{\mathtt{27}}}{{\mathtt{16}}}} = {\mathtt{1.687\: \!5}}$$
and so on by multiplying the result of the last sum by 1.5
then round the results as required to 1 decimal place
0.8 , 1.2 , 1.7 etc.
