40% will be from your test average which is 95

30% will be from your homework average which is 60

30% will be from your quiz average which is 70

Calculating based on these weights:

Fantom [35]

Answer:

x= 3,2

Step-by-step explanation:

10 ----------------  100%

x   ----------------  32%

x=\frac{10\times32\%}{100\%}

x=\frac{10\times32}{100}

x=\frac{320}{100}

x=\frac{32}{10}

x=\frac{32\div2}{10\div2}

x=\frac{16}{5}

x=3,2
