Pizzas cost $8 and sandwiches cost $2.50
Answer:
assume an approximate value for the variable that will simplify the equation.
solve for the variable.
use the answer as the second approximate value and solve the equation again.
repeat this process until a constant value for the variable is obtained.
(10 + 9) x (3 - 1) x 2 = +75
19 x 2 x 2
76
76 > 75
Answer:
