Every point on the x-axis has y-coordinate 0.
Let y = 0, and solve for x.
y = -5x + 5
0 = -5x + 5
5x = 5
x = 1
The line crosses the x-axis at x = 1.
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
