Question

Michael has $15.00 to spend on chocolates. The price of each type of chocolate is given below:

Fudge Centres: $0.60 Nut Clusters: $0.75 Truffles: $0.80

2. Michael decides to buy all three types of    

     chocolates, instead of choosing just one 

     type. 

a) If Michael buys the same number of all three types, how many can he buy sand stay within his budget?

b) Exactly how much will Michael spend?

c) Write an algebraic expression that represents the total amount Michael will spend. Then substitute for the variables and evaluate your expression. How does this amount compare with your amount in part (b)?

Answer 1

0.60 X + 0.75 X + 0.8 X = 15.00

2.15x = 15

215 x = 1500

x = 6.97674418604...

0.6*6 + 0.75*6 + 0.8 * 6 =

3.6 + 4.50 + 4.80 = 12.90

note that there is $2.10 left, but an extra

of each candy cannot be purchased because it

is a nickel short: 0.60 + 0.75 + 0.8 = 2.15

6 of each candy
