Question

Write a numerical expression in the first box that represents the number of points earned or lost each round.then write Andy's final point total at the end of the competition in the second box.

Answer 1

In the first round, Andy has -320 times 1/2, which corresponds to

`-320*(1)/(2)=-(320)/(2)=-160`

In the second round, Ansy has

`710*(1)/(4)=(710)/(4)=(355)/(2)`

which corresponds to 177.5 (in decimals).

Finally, Andy's final point is

`-320*(1)/(2)+710*(1)/(4)-500`

which is equal to

`-160+177.5-500=-482.5`

that is, Andy's final point is - 482.5.
