Philip bought apples from the grocery store for 2.20 per pound. if he bought 2.5 pounds of apples on monday and 1.2 apples on tuesday, how much did he spend on apples in total?

First you multiply 2.20 and 2.5 which gives you 5.5, then you multiply 2.20 and 1.2 which gives you 2.64, after the multiplying, you add your totals (5.5 + 2.64) and that equals 8.14. So he spent a total of $8.14 on apples.

1.       The price of an apple is 2.20 dollars per pound.
Now, Philip bought 2.5 apples on Monday and another 1.2 pound apples on Tuesday.
Solve for the total amount that Philip spent on buying apples>
1 pound = 2.20 dollars
Monday
=> 2.5 pounds
=> 2.5 * 2.2 = 5.5 dollars
Tuesday
=> 1.2 pounds
=> 1.2 * 2.2 = 2.64 dollars
Total
=> 2.64 + 5.5 = 8.14 dollars.
Thus, he spent 8.14 dollars for the apples.
