Question

1. use the formula $f=\frac{9}{5}c + 32$ to find the equivalent fahrenheit temperature if the expected high today is $10^{circ}c$.

a. $75.6^{circ}f$
b. $37.6^{circ}f$
c. $50^{circ}f$
d. $23.3^{circ}f$

Explanation:

Step1: Substitute C value

Given $C = 10$, substitute into $F=\frac{9}{5}C + 32$. So $F=\frac{9}{5}\times10+32$.

Step2: Calculate multiplication part

$\frac{9}{5}\times10 = 9\times2=18$. Then $F = 18+32$.

Step3: Calculate addition part

$18 + 32=50$.

Answer:

C. $50^{\circ}F$
