Answer:

Hi my lil bunny!

❀ _____.______❀_______._____ ❀

\frac{3 . 20}{5 . 20} = \frac{60}{100}

  2. 0.61 = \frac{61}{100}
  3. 0.62 = \frac{31}{50}
  4. 0.63 = \frac{63}{100}
  5. 0.64 = \frac{16}{25}
  6. 0.65 = \frac{13}{20}

Serena brought a total of 135 notebooks and pencils for her students. Each notebook cost 1.75 and each pencil cost 0.35. The tot
natima [27]

Answer:

81 pencils

Step-by-step explanation:

1. Set up variables

Pencils = p

notebooks= n

2. Set up a system of equations

p+n= 135                             (The amount of supplies bought)

1.75n +0.35p = 122.85       (Equation for the cost)

3. Solve the system of equations (I'll use substitution)

    a)p= 135-n  (I just rearranged it)

    1.75n + 0.35p= 122.85

     b) Substitute the first equation into the second)

    1.75n + 0.35(135-n) = 122.85

     c) Solve!

    1.75n + 47.25 - 0.35n = 122.85

    1.4n = 75.6

     n= 54

Serena bought 54 notebooks!

4. Substitute the number of notebooks into the first equation

p +n = 135

p + 54= 135

p = 81

Serena bought 81 pencils!!!

I hope this helps!!!!
