Let's assume money in Josie's purse to begin with as 'x'
There are 18 markers
Each marker cost $1.20
so, we can find total cost of markers
Total cost of markers = ( total number of markers)*(price of each marker)
so, we can plug value
Total cost of markers is
$
now, we are given
Josie spent 4/7 of the money in her purse on some books
the rest of the money on 18 markers
so, rest money is
and this rest money is total cost of markers
so, we can set them equal and then we can solve for x
So, total money in Josie's purse in beginning is $50.4..........Answer
Answer:
3rd and 4th option
Step-by-step explanation:
-1 times -1 is 1 and multiply that by another -1 and you get -1

Answer:
Step-by-step explanation:
we are to distinguish between
dependent variable independent variable
vs
response variable explanatory variable
An independent variable is one which is not affected by any other variable for example, the amount we spend, the time we study ,etc.
An explanatory variable is a type of independent variable but not fully independent but depends on some factors.
Though explanatory and independent variables are practically used interchangeably the main difference is explanatory variable is not independent but explains the variations in the response varaible.
