It costs twelve dollars to get in to the fair. Tickets for rides cost extra and are d dollars each. If Tyra buys 20 tickets, how much would it cost her for the fair?

20d + $12

Step-by-step explanation:

Given the following information :

Cost of getting into the fair or fair entry cost = $12

Tickets for ride = $d per ride

Number of tickets purchased = 20

Total cost for the fair =?

Total cost for the fair :

( entry cost + ticket cost)

Ticket cost = (number of tickets purchased * cost per ticket)

Ticket cost = (20 * d) = 20d

Entry cost = $12

Total cost:

$12 + 20d

why do wages differ across industries

step-by-step explanation :

micro economists are concerned with economics on an industry or individual firm basis.

macro economists are concerned with national and international level

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.
