Olivia bought a notebook for $12.50 and 9 pens. If her total was $43.73, how much was each pen?

• 12.5x +9 = 43.73

• 73.43 = 12.5x + 9

• 12.5 - 9x = 43.73

• 43.73 = 12.5 + 9x

12 + y = -15

• y = -27

• y = 27

• y = 3

• y = -3

Translate this sentence: Seven more than three times a number is 19.

Two less than 4 times a number is -18.

• 4x - 2 = -18

• 2x + 4 = -18

• 4x - 2 =-18

• 2 < 4x - 18

• h minus five plus m equals one-fourth of h.

• h minus the product of five and m equals one-fourth of h.

• h minus the sum of five and m equals one-fourth of h.

• h subtracted from five plus m equals one-fourth of h.

Katrina goes to a food truck for lunch and buys 6 corn dogs. She spends $21. Write and solve an equation to find the cost of each corn dog.

• 21 = 6c

  c = $3.50

• 21 = 6 + c

  c = $15

• 21c = 6

  c = $3.50

• 21c = 6

  c = $0.29
