Question

smoothie sales are on fire. the price is $3 for an adult and $1 for children. if 260 smoothies were sold for a total of 675.00 how many adults purchased smoothies? how many children?

Answer 1

• 207.5 adult
• 52.5 children

Explanation:

If "a" represents the number of adult smoothies sold, then 260-a is the number of smoothies sold to children. The total revenue is ...

3a +1(260-a) = 675

2a +260 = 675 . . . . . . eliminate parentheses

a + 130 = 337.5 . . . . . . divide by 2

a = 207.5 . . . . . . . . smoothies sold to adults

260-a = 52.5 . . . . . smoothies sold to children

For the given numbers, this is the way it works out. The "half" values suggest there is a typo somewhere, possibly in the curriculum material. Talk to your teacher about this one.
