Kader and Cam are sharing the cost of dinner in a ration of 2:5. Kader only wants to spend a maximum of $20 how much can dinner cost?

To find out how much dinner can cost, we need to first determine the total ratio of Kader's share to Cam's share. The total ratio is 2 + 5 = 7.

Next, we can find out the cost of dinner by dividing the total amount that Kader wants to spend by his share of the ratio. $20 / 2 = $<<20/2=10>>10.

Therefore, dinner can cost a maximum of $10.

To find out the maximum cost of dinner, we need to determine Kader's share.

Let's represent Kader's share as "2x" and Cam's share as "5x", where "x" is a common ratio factor.

Since Kader wants to spend a maximum of $20, we can set up the following equation: 2x <= 20.

Simplifying the equation, we have: x <= 10.

To find the maximum cost of dinner, we need to find the value of "5x" when "x" is at its maximum value.

5x = 5 * 10 = $<<5*10=50>>50.

Therefore, the dinner can cost a maximum of $50.

To find out how much dinner can cost, you need to divide the maximum amount Kader wants to spend by his share of the ratio.

In this case, Kader's share of the ratio is 2. So, you need to divide $20 by 2.

$20 รท 2 = $10

Therefore, dinner can cost a maximum of $10.
