### Instruction:
 Rose ni msanii anayetaka. Anataka brashi ya rangi inayogharimu $2.40, seti ya rangi inayogharimu $9.20, na easel inayogharimu $6.50 ili aweze kufanya michoro. Rose tayari ana $7.10. Anahitaji pesa ngapi zaidi?


### Response:
 Gharama ya jumla ya brashi ya rangi, rangi, na easel ilikuwa $2.40 + $9.20 + $6.50 = $<<2.4+9.2+6.5=18.10>>18.10.
Rose anahitaji $18.10 - $7.10 = $<<18.10-7.10=11>>11 zaidi.
