Answer 1

Answer: a) 30, b) 120

Step-by-step explanation:

Since we have given that

Let the number of points Scored by Dwayne be 'd'.

Number of points in the last basket ball game = 55 points

According to question, we get that

$d+10=55\\\\d=55-10\\\\d=45$

Let the number of points that Chris's score be 'c'.

Number of points Lebron scored = 45

According to question, number of points scored by Chris is given by

$c+15=45\\\\c=45-15\\\\c=30$

a. How many points did Chris score during the game?

c = 30

b. If these are the only three players who scored, what was the team’s total number of points at the end of the game?

$45+45+30=90+30\\\\=120$

Hence, a) 30, b) 120
