\frac{x}{25}=84% \\  \frac{x}{25}=.84 \\ 25( \frac{x}{25})=(.84)(25) \\ x=21
Maria got 21 correct.

Number wrong = Total - Number right
y = 25 - 21
y = 4

Maria got 4 wrong.

Hope this helps!

To see how much she got correct we need to do
(84/100)×25=21
so she got 21 correct out of 25
so 25-21=4
so she got 4 wrong

A jar contains 1,200 M&amp;M's and everyday your family eats 1/5th of the candies. After how many days will there be 314 M&amp;M
mrs_skeptik [129]
The equation is 314 = 1,200 - 240x

1,200 is the number of M&M's it starts with
The problem said the family eats 1/5th of the candy every day
1/5 of 1,200 is 240
It is a -240 because the amount of m&m's is getting fewer each day
The x stands for the number of days

Sorry but I'm not sure if I could answer your problem exactly
The answer is 3.69 days
Because there isn't an exact day that there would exactly 314 M&M's left
