Final answer:
The correct equation representing the amount of money Tony has in terms of hours worked is m = 20 + 10h, where 20 is Tony's initial savings and 10h is the money earned from working h hours. Option A.
Step-by-step explanation:
Tony has initially saved $20 and earns $10 for every hour he works. To represent this situation mathematically, we need to construct a linear equation with money earned (m) as the dependent variable and hours worked (h) as the independent variable.
The correct equation is m = 20 + 10h. Here, 20 represents the initial savings and 10h represents the earnings per hour multiplied by the number of hours worked.
Comparing with the options provided, the correct option is:
A. m = 20 + 10h
