Answer

11.

Explanation:

Step1: Find cost per envelope

Cost per envelope = $\frac{70}{100}=0.7$ cents.

Step2: Calculate cost of 250 envelopes

Cost of 250 envelopes = $0.7\times250 = 175$ cents. Since 100 cents = 1 dollar, $175$ cents = $$1.75$.

Answer:

$1.75$

Brief Explanations:

The word "If" creates a conditional - statement. If you are careful, then it is possible to thread a needle. The other words do not fit the logical structure of the sentence as well. "Because" and "Since" imply a causal relationship, and "Although" and "However" imply contrast.

Answer:

If
