Answer 1

Anne: 57
Josh: 75
Claire: 25

Add them all up and you get 157

Answer 2

Answer:

• 37, 60, 30

Step-by-step explanation:

Ann - a, Josh - j, Claire - c

• a = j + 7
• j = 2c
• a + j + c = 157

Substitute a and j into last equation and solve for c:

• (j + 7) + 2c + c = 157
• 2c + 7 + 3c = 157
• 5c = 150
• c = 30

Find a and j:

• a = 30 + 7 = 37
• j = *30 = 60
