Answer:
122
Explanation:
Alice , Ben and Celine had 270 stickers altogether . Alice had 10 more stickers than Ben . Celine had thrice as many stickers as Alice .
where:
B = B
A = B + 10
C = 3A
All together equal 270 so:
B + A + C = 270
substitute in:
B + (B + 10) + 3(B + 10) = 270
B + B + 10 + 3B + 30 = 270
subtract 40 from both sides:
B + B + 10 + 3B + 30 - 40 = 270 - 40
B + B + 3B = 230
Combine left side:
5B = 230
divide both sides by 5:
5B/5 = 230/5
B =46
SO:
Using equations:
B = 46
A = 46 + 10 = 56
C = 3(56) = 168
check: 46 + 56 + 168 = 270 stickers total
