Elijah played in a golf tournament. For the first three days he averaged a score of -2. On the fourth day he shot a +2. What was his average for all four days
+3502 well sine she spent then you subtract 35.55-3.15-2.20-14.99 then you add 5 since her friend gave her 5 so the problem would like 35.55-3.15-2.20-14.99+5.00=20.21
+3502 for your second question it would be -1 all you have to do is add -2 for three days -2+-2+-2=-6 then add two for the fourth day you get -4 then divide -4 divided by 4 and oom answe
+6 $${\mathtt{35.55}}{\mathtt{\,-\,}}{\mathtt{3.15}}{\mathtt{\,-\,}}{\mathtt{2.2}}{\mathtt{\,-\,}}{\mathtt{14.99}}{\mathtt{\,\small\textbf+\,}}{\mathtt{5}} = {\frac{{\mathtt{2\,021}}}{{\mathtt{100}}}} = {\mathtt{20.21}}$$
+6 I think, that because the average is -2, and it were 3 days, it would be -6 total in 3 days, then he shot +2, that would be -4, there were for days so his final average would be -1. You would write it down like this:
$${\frac{\left({\mathtt{\,-\,}}{\mathtt{2}}{\mathtt{\,\times\,}}{\mathtt{3}}{\mathtt{\,\small\textbf+\,}}{\mathtt{2}}\right)}{{\mathtt{4}}}}$$ =
$${\frac{\left({\mathtt{\,-\,}}{\mathtt{6}}{\mathtt{\,\small\textbf+\,}}{\mathtt{2}}\right)}{{\mathtt{4}}}}$$=
$${\mathtt{\,-\,}}{\frac{{\mathtt{4}}}{{\mathtt{4}}}} = -{\mathtt{1}}$$
