23 regular coffees were served.
25% means 1/4
25% x 92 = 23 regular coffees were served.
92 - 23 = 69 decaf coffees were served.
2f + 2v = $12.50
8f + 2v = $29.00
-2f. - 2v = -12.50
8f + 2v = 29.00
6f = $16.50
f= $2.75 each flower bouquet
2(2.75) + 2v = 12.50
5.50 + 2v = 12.50
2v = $7.00
v = $3.50 each vase
