Faruq spends all of his income on tacos and milkshakes. His income is $100, the price of tacos is $10, and the price of milkshakes is $2. Put tacos on the horizontal axis and milkshakes on the vertical axis. The horizontal intercept for Faruq's budget line is

The correct answer is 10.

Step-by-step explanation:

Faruq spends all of his income ($100) on tacos and milkshakes.

Price of tacos is $10, and the price of milkshakes is $2.

Let Faruq buy x number of tacos (horizontal axis) and y number of milkshakes (vertical axis).

Total expenditure of Faruq is given by 10 * x + 2 * y.

Since Faruq does not save anything, therefore his expenditure is equal to his income.

Thus his budget line is given by 10 * x + 2 * y = 100.

To calculate the horizontal intercept for Faruq's budget line we consider y = 0, i. e. we want to calculate how many tacos Faruq would buy when he does not buy any amount of milkshakes.

Thus taking y = 0, we get

10 * x = 100

⇒ x = 10

Thus the horizontal intercept for Faruq's budget line is 10.
