Create a proportion.

[tex] \frac{4}{2.60} =\frac{7}{x} [/tex]

Cross multiply.

4x = 18.2

Divide both sides by 4.

x = 4.55

It will cost $4.55 to purchase 7 croissants.

First find out how much one croissant cost.

Divide the total for 4 croissants $2.60, by the amount of croissants there is (4).

2.60/4 = 0.65

Each croissants cost $0.65

Next, multiply the amount each croissant cost, and multiply to the amount there is.

$0.65 x 7 = 4.55

7 croissants cost $4.55

hope this helps
