Answer:

The revenue the store would make if it sold 1 costume is $46

The revenue the store would make if it sold 2 costumes is $92

The revenue the store would make if it sold 6 costumes is $276

The revenue the store would make if it sold 8 costumes is $368

Explanation:

We will use the ratio method to solve the question

∵ One costume store makes $184 in revenue by selling 4 vampire

costumes

∴ The ratio between the revenue and the number of vampire costumes

is 184: 4

Let us use this ration to find the revenue if the store sold 1, 2, 6, 8 costumes

→ Revenue → Vampire costumes

→ $184 → 4

→ $x → 1

→ By using the cross multiplication

∵ x × 4 = 184 × 1

∴ 4x = 184

→ Divide both sides by 4

∴ x = 46

The revenue the store would make if it sold 1 costume is $46

→ Revenue → Vampire costumes

→ $184 → 4

→ $x → 2

→ By using the cross multiplication

∵ x × 4 = 184 × 2

∴ 4x = 368

→ Divide both sides by 4

∴ x = 92

The revenue the store would make if it sold 2 costumes is $92

→ Revenue → Vampire costumes

→ $184 → 4

→ $x → 6

→ By using the cross multiplication

∵ x × 4 = 184 × 6

∴ 4x = 1104

→ Divide both sides by 4

∴ x = 276

The revenue the store would make if it sold 6 costumes is $276

→ Revenue → Vampire costumes

→ $184 → 4

→ $x → 8

→ By using the cross multiplication

∵ x × 4 = 184 × 8

∴ 4x = 1472

→ Divide both sides by 4

∴ x = 368

The revenue the store would make if it sold 8 costumes is $368
