Frankie purchased 3 video games for $x and a game system for $400. He spent a total of $510. 4 (a) Write an equation that can be used to determine the cost of one video game

Given:

Frankie purchased 3 video games for $x and a game system for $400.

He spent a total of $510.

To find:

The equation that can be used to determine the cost of one video game.

Solution:

We have,

Cost of game system (Fixed cost) = $400

Cost of 1 video game =

Cost of 3 video games =

Now,

Total cost = Cost of game system  + Cost of 3 video games

                =

                =

He spent a total of $510. It means, total cost is equal to $510.

Therefore, the required equation is .

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30
