Question

At Laser Tag Park, players earn 5 points every time they tag a member of the other team.
Each time a player hits one of the laser pods in the park, the player earns 15 points. At her
laser tag birthday party, Florence tagged members of the other team 19 times. She also hit a
laser pod 6 times. How many points did Florence earn by the end of the game?

Answer 1

Let "tagging a member of the other team" be $x$

And "hitting one of the laser pods in the park" be $y$

We know Florence did $x$ 19 times and did $y$ 6 times.

$19x+6y$

We know that for every $x$ there are 5 points, and for every $y$ there are 15 points. We just have to substitute the values on the above expression and operate

$19*5+6*15=185$

Florence earned 185 points by the end of the game
