Question

Paul spend 7.50 every day for 3 days which expression is the best choice to help her to terminate the total amount of money he spent

Answer 1

How about an informal solution....

If all 9 fruits were oranges, the cost would be 9 times 50 cents, a total of $4.50.

But the total cost was $4.10, which is 40 cents less than $4.50.

Since each apple costs 10 cents less than each orange, and since $4.10 is 40 cents less than $4.50, the number of apples must be 40/10 = 4.

Answer 2

7.50 x 3= m

m= the amount of money spent
