You are on a treasure-diving ship that is hunting for gold and silver coins. You reel in a wire basket that contains gold and silver coins, among other things. The basket holds no more than 50 pounds of material. Each gold coin weighs about 0.5 ounce, and each silver coin weighs about 0.25 ounce. You want to know the different numbers of each type of coin that could be in the basket.

Answer:

Inequality equation:

0.03125x + 0.015625y ≤ 50 pounds

Step-by-step explanation:

We convert the ounces to pounds

1 ounce = 0.0625 pound

For the gold coin = 0.5 ounce

1 ounce = 0.0625 pounds

0.5 ounce = x

x = 0.5 × 0.00625 pounds

x = 0.03125 pounds

For the Silver coin = 0.25 ounce

1 ounce = 0.0625 pounds

0.25 ounce = x

x = 0.25 × 0.00625 pounds

x = 0.015625 pounds

The basket holds no more than 50 pounds of material.

Let the number of gold coins = x

The number of silver coins = y

Hence: our inequality equation:

0.03125x + 0.015625y ≤ 50 pounds
