## Elementary Technical Mathematics

survival rate = $74.8\%$
RECALL: $R=\dfrac{P}{B}$ where $P$=part or amount (percentage), $B$=base, and $R$=rate The given problem has: $B= 250$ mallards $P= 187$ mallards Use the formula above to find the survival rate: $=\dfrac{187}{250} \\=0.748 \\=0.748 \times 100\% \\=74.8\%$
