Four students spent 12$on school lunch at thus rate what is the amount 10,students would spent on the same school lunch

(12/4) * 10 = ?

To find out how much 10 students would spend on the same school lunch, we need to determine the rate at which the 4 students spent the $12.

Given that 4 students spent $12, we can set up a proportion to find the amount 10 students would spend.

Let's call the amount 10 students would spend "x."

The proportion can be set up as:
4 students / $12 = 10 students / x

To cross multiply, we multiply the opposite values:
4 * x = 12 * 10

Simplifying the equation:
4x = 120

Finally, we solve for x by dividing both sides of the equation by 4:
x = 120 / 4 = $30

Therefore, if 4 students spent $12 on school lunch, 10 students would spend $30 on the same school lunch.
