Answer 1

yes he is correct

Explanation:

because first you add 38 + 77 =115 and then you multiply by 0.5, so 115 times 0.5 = 57.5

Answer 2

Jace is wrong

This how you do it: (19 + 77 x (0.5) )

Explanation:

Here, for each point scored, $0.5 is put in the jar.

Now, the point scored in the first game = 38 points

So, the amount put in the jar for 38 points = 38 x ( amount for 1 point)

= 38 x ( $0.5) = $19

So, after first game, jar has $19.

Now, the point scored in the(2 +3) game = 77 points

So, the amount put in the jar for 77 points = 77 x ( amount for 1 point)= 77 x ( $0.5) = 77 x (0.5)

So, after second and third game, jar has $ (77 x (0.5)).

Now, total amount in jar

= Amount after first game + Amount after second and third game

= 19 + 77 x (0.5)

But , here THE TOTAL AMOUNT given by Jace = 38+(77 x 0.5)

And 19 + 77 x (0.5) ≠ 38+(77 x 0.5)

$57.5
