Ari found four 1-dollar bills and 3 dimes under his bed. How much money did he find?

Of course, it is $4.30

I assume you know how much 4 $1 bills is.

now add 3 dimes to that.

To find out how much money Ari found, we need to add the amounts of the 1-dollar bills and the dimes.

The value of each 1-dollar bill is $1, so we multiply the number of 1-dollar bills (4) by the value of each bill ($1). This gives us 4 * $1 = $4.

The value of each dime is $0.10, so we multiply the number of dimes (3) by the value of each dime ($0.10). This gives us 3 * $0.10 = $0.30.

Now, we can add the value of the 1-dollar bills ($4) to the value of the dimes ($0.30) to find the total amount of money Ari found.

$4 (value of 1-dollar bills) + $0.30 (value of dimes) = $4.30.

Therefore, Ari found a total of $4.30.
