lana [24]

Answer:The inequality is

x greater than or equal to(>/=) 14

Step-by-step explanation:

Let x represent the possible cost of the full pizza. Tara eats 3 of the 10 slices and pays $4.20 for her share. This means that the amount of pizza that Tara ate is 3/10×x = 3x/10

Assuming that Tara has paid at least her fair share, therefore

3x/10 = 4.20

3x = 4.20 ×10 = 42

x = 42/3 = 14

This means that the total cost of the pizza is at least $14. The inequality

how much the pizza could have cost becomes

x greater than or equal to(>/=) 14
