Given that the cheese costs $$ \$22 $$ per kilogram, we first convert the gram amounts to kilograms.

Ella buys a $$ 75 $$-gram piece, so in kilograms she buys:
$$
0.075 \text{ kg} = \frac{75}{1000}
$$

Ali buys a $$ 250 $$-gram piece, so in kilograms he buys:
$$
0.250 \text{ kg} = \frac{250}{1000}
$$

Next, we compute the cost for each.

For Ella, the cost is:
$$
\$22 \times 0.075 = \$1.65
$$

For Ali, the cost is:
$$
\$22 \times 0.250 = \$5.50
$$

To find how much more Ali paid than Ella, we subtract:
$$
\$5.50 - \$1.65 = \$3.85
$$

Thus, Ali paid $$ \$3.85 $$ more than Ella.
Ali paid \$3.85 more than Ella.

Suppose cheese costs per kilogram. Ella buys a 75 -gram piece of cheese and Ali buys a 250 -gram piece of choese.

How much more did Ali pay for his cheese?
