​Regrind, Inc. regrinds used typewriter platens. The cost per platen is ​$1.10. The fixed cost to run the grinding machine is ​$195 per day. If the company sells the reground platens for ​$6.10​, how many must be reground daily to break​ even?

39

Explanation:

The number that must be reground to break even will be calculated thus:

The total cost for x platens will be:

C(x) = 195 + 1.1x

The total revenue for x platens will be:

R(x) = 6.1x

The equation for breakeven will be:

C(x) = R(x)

195 + 1.1x = 6.1x

6.1x - 1.1x = 195

5.0x = 195

x = 195/5.0

x = 39

To breakeven, 39 must be reground daily.

the correct answer is:

it required the president to inform congress within forty-eight hours of any new troop commitment.

the war powers resolution (1973) is a federal law designed to limit the u.s. president’s ability to initiate or intensify military actions abroad without the approval of the congress.

it establishes that the president can send armed forces into action abroad only by declaration of war by congress, statutory authorization, or in case of a national emergency created by attack upon the united states, its territories or possessions, or its armed forces.

it requires the president to notify congress within 48 hours of sending armed forces to military action.
