In a video game, minerals are mined at a rate of 0.8 minerals per second. the player starts off with 250 minerals. this can be represented by m(s) = 250 + 0.8s. what does m(45) represent? the time to mine 45 minerals the number of minerals mined in 45 seconds the time to mine 250 minerals none of these

The number of minerals mined in 45 seconds

Explanation:
The given equation is:
M(s) = 250 + 0.8s

Let's check each term in this equation:
M(s) represents the minerals mined in s seconds
250 is the initial value
0.8s represents the rate of increase of the minerals mined in s seconds

Now, based on the above:
M(45) would represent the minerals mined at s=45 seconds
