Write an equation that indicates you can spend exactly 45 per day for rental fees

An equation that indicates you can spend exactly $45 per day for rental fees is,

Step-by-step explanation:

Let x represents the days and y represents total the rental fees.

As per the statement:

you can spend exactly $45 per day for rental fees.

In 1 day you spend  = $45 rental fees.

then

in x days = 45 x

we have to find an equation that indicates you can spend exactly $45 per day for rental fees

since, y represents the total rental fees,.

⇒ y= 45x

Therefore, an equation that indicates you can spend exactly $45 per day for rental fees is,

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.
