Define a variable, set up an equation, then solve.
Sean and Evan are selling rolls of wrappign paper to raise money for new football uniforms. Evan has sold seven more than one-half the number of rolls that Sean has. If they have sold a total of 121 rolls, how many has Evan sold?
x - Rolls sold by Evan
Answers
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 1/2x + 7 rolls.
Therefore, we have:
x + (0.5x + 7) = 121
1.5x = 121 - 7
x = 114/1.5
x = 76

Enter your answer as a mixed number in simplest form.
Answers
ex:
The mixed number is [tex]-14 \frac{4}{7}[/tex]
What are Mixed Numbers?
A mixed number is a whole number, and a proper fraction represented together. A mixed number is formed by combining three parts: a whole number, a numerator, and a denominator. The numerator and denominator are part of the proper fraction that makes the mixed number.
Given data ,
[tex]\frac{p}{1\frac{3}{7} } = -10.2[/tex]
To solve for p ,
Multiply by [tex]1\frac{3}{7}[/tex] on both sides we get ,
p = [tex]-10.2[/tex] × [tex]1\frac{3}{7}[/tex]
Now , [tex]1\frac{3}{7}[/tex] can be written as the improper fraction form as [tex]\frac{10}{7}[/tex]
So ,
p = [tex]-10.2[/tex] × [tex]\frac{10}{7}[/tex]
p = [tex]\frac{-102}{7}[/tex]
Now , the improper fraction [tex]\frac{-102}{7}[/tex] can be represented by the mixed number as [tex]-14 \frac{4}{7}[/tex]
Hence , The mixed number is [tex]-14 \frac{4}{7}[/tex]
