Sean and Evan are selling rolls of wrapping paper to raise money for the new football team uniforms. Evan has sold seven more that one-half the number of rolls that Sean has. If they sold a total of 121 rolls, how many has Evan sold? Help Please:)

Respuesta :

Solution: Let x be the number of rolls sold by Sean.

We are given that Evan has sold 7 more that one-half the number of rolls that Sean sold.

Evan has sold [tex]\frac{1}{2} x+7[/tex] rolls.

Therefore, we have:

[tex]x+(0.5x+7) =121[/tex]

[tex]1.5x=121-7[/tex]

[tex]x=\frac{114}{1.5}[/tex]

[tex]x=76[/tex]

Therefore, Sean has sold 76 rolls and Evan has sold [tex]121-76=45[/tex] rolls
