For each question, use the specific criteria to award a maximum of four credits. Unless<br />

otherwise specified, mathematically correct alternative solutions should be awarded<br />

appropriate credit.<br />

[3] Appropriate work is shown, but one computational error is made.<br />

or<br />

[3] Appropriate work is shown to find 15,600,000 and 11,232,000, but the<br />
