At a cafe, the bishop family pays $12 for a salad, a fruit bowl, and two sandwiches. the cortez family pays $14 for two salads and two sandwiches. the donovan family pays $14 for a salad and three fruit bowls. what is the price of a fruit bowl at the cafe? $2 $3 $4 $5?

$3

Explanation:

S=Price of a Salad

F= Price of a fruit bowl

W= Price of a Sandwiches

We build a set of equations with the information given for each family as follows:

1S+1F+2W=12    eq.1

2S+2W=14         eq.2

1S+3F=14            eq.3

Clearing w from eq.2

W=7-S

Clearing F from eq.3

Replacing eq.2 and eq. 3 in eq. 1

S=5

Then,

F=9/3

F=3

u = 30

continuing your method

= +

subtract from both sides

= - thus

= -

= ⇒ u = 30
