Allushta [10]
5 buckets at $2.89 = 5($2.89) = $14.45
10 brushes at $7.91 = 10($7.91) = $79.10
48 towels at $0.36 = 48($0.36) = $17..28

These three added together makes $110.83.  This leaves us $144.08-$110.83=$33.25 for the cost of the case of air fresheners.

Winston would need to sell 14 more hot dogs to earn $175

Step-by-step explanation:

The given is:

  • Winston earns $140 by selling 56 hot dogs
  • He is using the same rate for the cost of one hot dog
  • He want to earn $175

We need to find how many more hot dogs would Winston need to sell to earn $175

∵ The he sold 56 hot dogs for $140

- Find the price of each hot dog by dividing 140 by 56

∴ The price of each hot dog = 140 ÷ 56 = 2.5

∴ The price of each hot dog is $2.5

∵ He need to earn $175

∵ He sells all hot dogs by the same price

- Divide 175 by 2.5 to find the number of the hot dogs

∵ 175 ÷ 2.5 = 70

∴ He must sell 70 hot dogs to earn $175

∵ He already sold 56

- Subtract 56 from 70 to find how many more hot dogs he

   needs to sell

∵ 70 - 56 = 14

∴ He must sell another 14 hot dogs to earn that money

Winston would need to sell 14 more hot dogs to earn $175
