Sahaara bought a total of 10 Starbucks drinks for her peers. Chloe took half the Starbucks drinks while Avery had 4 less than Chloe. How many Starbucks did Sahaara have left? Write a full algebraic expression before solving, with x representing how many drinks are left.
x = 10 - (Chloe + Avery)
x = 10 - ((10 ÷ 2) + (10 ÷ 2 -4))
x = 10 - (5 + 1)
x = 4
