Question

Help, please!!!

A grocery store sign indicates that bananas are 3 for $1.50, and a sign by the oranges indicates that they are 5 for $3.00. Find the total cost of buying 2 bananas and 4 oranges.


(Screen shot question number 2 "How many laps can he swim in 6 minutes?")

Answer 1

3.40 and 15

Explanation:

3 for 1.50 means 1 is 50 cents each.

5 oranges for 3 dollars mean each one is 60 cents.

So this equation is 4(.60)+2(.50)

=3.40

For the swimming problem,

divide the 2 and 5 and you should get 2.5.

Multiply 2.5 by 6 to get 15.

Here are the answers for the missing blanks

(2.5, 1) (5, 2) (7.5, 3) (10, 4) (12.5, 5)
