Question

A kid is selling cupcakes, each cupcake sold for $1.25 and cookies for $1.75, Jason sold 92.50 worth of cake and cookies if he sold both combined how many cakes were sold and how many cookies

Answer 1

Set x and y to be the number of cupcakes and cookies, respectively.

Therefore, according to the question,

$Cost=1.25x+1.75y$$\Rightarrow1.25x+1.75y=92.50$

There is only one provided equation; therefore, we cannot determine x and y but just x in terms of y or vice versa. To determine x and y, more information is needed.

Solving for x,

$x=\frac{92.50-1.75y}{1.25}$
