Mieko has 4 times as many pencils as Holden. Since Holden has 8 pencils, we can calculate the number of pencils Mieko has as follows:
Mieko's pencils \( p = 4 \times 8 = 32 \).
Now we can complete the comparison sentence:
Mieko has \( p \) pencils, which is \( 32 \) pencils.
So, the comparison sentence would be:
Mieko has more pencils than Holden.
In terms of the comparison, you can say:
Mieko's \( p \) (32) > Holden's (8).
