A movie theater charges $7 for adults, $5 for school-age children, and $3 for babies. A group of people went to the theater. There were the same number of school-age children as babies and the number of adults was the same as school-age children and babies combined. If the group paid $1562, how many babies were in the group ?
Please type your subject in the School Subject box. Any other words, including obscure abbreviations, are likely to delay responses from a teacher who knows that subject well.
same number of school-age children as babies
x=number of school-age children
x=number of babies
number of adults was the same as school-age children and babies combined
y=number of adults
$7(2x) + $5(x)+ $3(x) = $1562
