Answer:
Becky scored 28
Explanation:
Let Min's score be m.
Becky's score is twice Min's score, so Becky's score is 2m.
Together, Min and Becky scored m + 2m. Together, they scored 42.
That means that m + 2m must equal 42.
m + 2m = 42
3m = 42
m = 14
Min scored 14.
Becky: 2m = 2(14) = 28
Becky scored 28
