Oranges cost 21 cents each. Alex buys x oranges and Bobbie buys (x+2) oranges.
The total cost of these oranges is $4.20.

Step-by-step explanation:

x be the number of oranges

x + (x+2) = $4.20

2x + 2 = 4.20

2x = 2.20

x = 1.1

if you wanna check,

1.1 + (1.1 + 2) =$4.20

1.1 + 3.1 =$4.20

4.2 =$4.20

Alex = x = 1.1 oranges

Bobbie = (x+2) = 1.1 + 2 = 3.1 oranges
