Terrence is learning how to play the piano. Each lesson costs $18.50, and he usually pays for a whole month in advance. If he has 4 lessons scheduled for next month, how much will he pay?

$74

Step-by-step explanation:

If each lesson is 18.50 and he has 4 lessons next month, you multiply 18.50 by 4 which you will get 74. So he has to pay $74

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.
