Aculinary club earns $1190 from a dinner service. they sold 34f adultadult meals and 51 student meals. an adult male cost twice as much is a student meal. what is the cost of an adult meal.

$20

Step-by-step explanation:

Let S = student meal cost

Let A = adult meal cost

We know that the adult cost is twice the student cost

Formula 1:

A= 2S

We also know that there were 34 adult tickets and 51 student tickets

Formula 2:

34A + 51S = $1,190

Substitute the value of A from formula 1 into formula 2

34(2S) + 51S = $1,190

68S + 51S = $1,190

119S = $1,190

Divide by 119

S = $10

And

A = 2S

A = 2($10)

A = $20

answer: group b.
