Question

1. kate has 79 more envelopes to stamp before she can send off her wedding invitations. if she is sending 234 invitations in all, how many has she stamped so far?

Explanation:

Step1: Define the total and remaining.

Let total envelopes be \( T = 234 \), remaining envelopes be \( R = 79 \), and stamped envelopes be \( S \). The relationship is \( T = S + R \), so \( S = T - R \).

Step2: Substitute values.

Substitute \( T = 234 \) and \( R = 79 \) into the formula: \( S = 234 - 79 \).

Step3: Calculate the result.

\( 234 - 79 = 155 \).

Answer:

155
