Answer:
$5250
Step-by-step explanation:
multiply the cost by the number of people
5/7 ÷ 1/3 = 5/7 × 3/1 = 15/7
Here how it goes, 12 boys to 8 girls is 3:2 in ratio form but since u adding 2 more girls then 8 girls + 2 girls = 10 girls so now its 12 boys + 10 girls so your answer in final would be 6:5.
