8 rental movies will make the costs of the two stores be the same

Step-by-step explanation:

- Mr Cosgrove is comparing movie rentals deals

- Netflix charge a flat rate of $8.50

- Blockbuster charge $4.50 plus a $0.50 per movie

- We need to find how many movie rental make the costs of the two

  stores will be the same

- Assume that the number of rental movies is m

∵ Blockbuster charge $4.50 plus a $0.50 per movie

∴ Blockbuster cost = 4.50 + 0.50 m

∵ The cost of Netflix = 8.50

- Equate the two costs to find the number of the rental movies

∵ 4.50 + 0.50 m = 8.50

- Subtract 4.50 from both sides

∴ 0.50 m = 4

- Divide both sides by 0.50

∴ m = 8 movies

8 rental movies will make the costs of the two stores be the same
