•  $8r-4=40$  

•  $8r=44$  

•  $8r-32=40$

A daycare charges a base fee of $3 plus $0.50 per minute for late pick-ups. Barry had to pay $10.50 for a late pick-up. Barry uses the equation,  $10.50=0.50a+3$  to represent the situation.
What does the variable  $a$  represent in the equation?

• The number of minutes Barry is late to pick-up.

• The part of the cost that depends on the number of minutes late.

• The number of dollars per minute late.

Gina is building a brick wall. Each row of bricks is 6.5cm tall except that the top row is 1cm shorter because it has no mortar. She wants the wall to be 259cm tall.

Which equation can we use to determine  $r$ , the number of rows of bricks Gina needs in her wall? 

• $6.5\left(r-1\right)=259$

• $6.5r-1=259$

• $6.5r-r=259$

• $6.5\left(r-1\right)+1=259$

Step 3                  $j=-6$  

• Step 1

• Step 2

• Step 3

• Carly didn't make a mistake.

Frank tried to solve an equation step by step
 $-5=5\left(d+4\right)$  

Find Frank's mistake.

Step 1      $-5=5d+20$  
Step 2                  $15=5d$  
Step 3                     $3=d$  

• Step 1

• Step 2

• Step 3

• Frank did not make a mistake.

Solve the equation: y + 3 = 8

• y = 5

• y = 6

• y = 7

• y = 8

Solve the equation: c + 1/8 = 1/2

• c = 2/10

• c = 3/8

• c = 1/6

• c = 5/8
