In Lucy's coin collection, 15% of the coins are quarters.
stepan [7]

The total number of coins in Lucy's coin collection is equal to 80 coins.

  • Let the total number of coins be C.

<u>Given the following data:</u>

  • Percentage of quarters = 15%
  • Total number of quarters = 12 quarters

To the total number of coins in Lucy's coin collection:

Since the percentage of the quarters in Lucy's coin collection is equal to fifteen percent (15%) of the total number of coins. Thus, we would multiply the total number of coins by 15% and equate it to 12 quarters.

<u>Total number</u><u> of </u><u>coins</u><u>:</u>

\frac{15}{100} \times C = 12\\\\15C=12 \times 100\\\\15C =1200\\\\C=\frac{1200}{15}

C = 80 coins.
