Answer:
Step-by-step explanation:
a + d + m + r = 16
a = d + 3......d = a - 3
a = m + 2.......m = a - 2
m = r + 1.......r = m - 1.......r = (a - 2) - 1......r = a - 3
a + (a - 3) + (a - 2) + (a - 3) = 16
4a - 8 = 16
4a = 16 + 8
4a = 24
a = 24/4
a = 6 <==== andrew scored 6
d = a - 3.....d = 6 - 3.....d = 3 <=== danielle scored 3
m = a - 2......m = 6 - 2.....m = 4 <==== mel scored 4
r = a - 3......r = 6 - 3 ......r = 3.......renee scored 3
