Question

question 7 2 pts in 2015, a high paid actress made $52,000,000. a second actress made 3.55×10⁷ dollars. find the combined amount of their salaries, and express your answer in both scientific notation and standard notation: ☐ 8.75 × 10⁸ ☐ 875,000,000 ☐ 87,500,000 ☐ 8.75 × 10⁷

Explanation:

Step1: Convert salaries to same notation

First, convert $52,000,000$ to scientific notation. $52,000,000 = 5.2\times10^{7}$. The second actress's salary is $3.55\times10^{7}$.

Step2: Add the two salaries in scientific notation

Add the coefficients: $5.2 + 3.55 = 8.75$. The exponent remains $10^{7}$ (since the exponents are the same). So in scientific notation, the combined salary is $8.75\times10^{7}$.

Step3: Convert scientific notation to standard notation

To convert $8.75\times10^{7}$ to standard notation, we move the decimal point 7 places to the right: $8.75\times10^{7}=87,500,000$.

Answer:

Scientific notation: $8.75\times10^{7}$; Standard notation: $87,500,000$
