### Instruction:
 Albert anataka brashi ya rangi inayogharimu $1.50, seti ya rangi inayogharimu $4.35, na easel ya mbao inayogharimu $12.65. Albert tayari ana $6.50. Anahitaji pesa ngapi zaidi?


### Response:
 Albert anataka brashi ya rangi inayogharimu $1.50, seti ya rangi inayogharimu $4.35, na easel ya mbao inayogharimu $12.65, hivyo 1.5+4.35+12.65 = $<<1.5+4.35+12.65=18.50>>18.50.
Albert tayari ana $6.50, hivyo anahitaji 18.5-6.5 = $<<18.5-6.5=12>>12.
