Set up an expression:
Bianca has four more than twice as many
hair bows as Hannah

because 2+2 is 4

Step-by-step explanation:

2h+4=b

Step-by-step explanation:

h stands for how many bows hannah has, and b stands for how many bows bianca has. bianca has four more than twice the amount of bows as hannah, so you double hannah's amount, and add four!
