They will need 25 boy costumes and 35 girls costumes.

Step-by-step explanation:

There are x boys.

There are x + 10 girls.

Altogether, there are x + x + 10 students.

Altogether, there are 60 students, so

x + x + 10 = 60

2x + 10 = 60

2x + 50

x = 25 (boys)

x + 10 = 35 (girls)

Answer: 35 girl costumes, 25 boy costumes.

Step-by-step explanation:

60 split into 2 groups is 30 each.

Add 5 to one group and subtract 5 from the other to get a difference of 10.

Girls group is 30+5=35

Boys group is 30-5=25
