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

7.50 x 3= m 

m= the amount of money spent

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.

W-14=t. that i think is the answer idk
