Claudia is making 12 serving for 5 people and she needs to make enough for 10. which means that she needs to make 12 + 12 = 24 servings for 10 people.
dessert mold holds 8 servings. 24 / 8 = 3
the minimum number of these molds is 3.
100% + 25% is 120% then 120 as a decimal 1.20 then you do 1.20 x 65 = 78
soo the selling price is $78
Answer:
length = 13 ft
Width = 3 ft
Step-by-step explanation:
Width = w ft
Length = ( w +10 ) ft
Area = 39 square ft
length * width = 39
(w +10)* w = 39
w *w + 10*w = 39
w² + 10w - 39 = 0
w² + 13w - 3w - 3*13 = 0
w(w + 13) - 3(w + 13) = 0
(w + 13) (w - 3) = 0 {Ignore w + 13 , as measurement cannot be in negative}
w - 3 = 0
w = 3
length = 3 +10 = 13 ft
