The expression that represents the number of stamps that Jenna has is 2x - 20

Step-by-step explanation:

Let us revise some algebraic expressions

  • a is 5 more than b ⇒ a = b + 5
  • a is 3 less than b ⇒ a = b - 3
  • a is twice b ⇒ a = 2 b
  • The sum of a and b ⇒ a + b
  • The difference of a and b ⇒ a - b
  • The quotient of a and b ⇒ a ÷ b
  • The product of a and b ⇒ a × b

∵ Jenna and Callie collect stamps

∵ Jenna has 20 less than twice the number of stamps that Callie has

- Assume that Callie has x stamps, that means to find the number

  of stamps of Jenna multiply x by 2 and subtract 20 from the product

∵ Callie has x stamps

∵ Twice means × 2

∴ Jenna has = 2(x) - 20

∴ Jenna has = 2x - 20

The expression that represents the number of stamps that Jenna has is 2x - 20
