Full solution

Q. This equation shows how the total score in a game is related to the number of points scored per level.

s = 100l + 250

. The variable

l

represents the levels completed, and the variable

s

represents the total score. What is the total score after completing

3

levels?

Identify value for $l$ : Identify the value for $l$ . We know $l = 3$ because $3$ levels are completed.
Plug in value for $l$ : Plug in the value for $l$ into the equation $s = 100l + 250$ . So, $s = 100 \times 3 + 250$ .
Calculate total score: Calculate the total score. $s = 100 \times 3 + 250 = 300 + 250$ .
Add up scores: Add up the scores. $s = 300 + 250 = 550$ . So, the total score after $3$ levels is $550$ .
