10. Find the amount spent

For an art workshop, 25 students each need 3 sheets of coloured paper at \(₹\)16 per sheet and 2 paintbrushes at \(₹\)25 each. In addition, the teacher buys 5 bottles of paint at \(₹\)90 each for everyone to share. The school reimburses \(₹\)500 of the total expense.

(a) Write an arithmetic expression for the amount spent after the reimbursement.

(b) Find the amount actually spent.

(c) If the remaining cost is shared equally among the 25 students, find the contribution of each student.

 

Ans: 

 

(a) \(25 \times [(3 \times 16) + (2 \times 25) - (5 \times 90) - 500]\)\(25 \times [(3 \times 16) + (2 \times 25) - (5 \times 90) + 500]\)\((25 \times 3 \times 16) + (25 \times 2 \times 25) + (5 \times 90) - 500\)\((25 \times 3 \times 16) + (25 \times 2 \times 25) + (5 \times 90) + 500\)

 

(b) \(₹\)

 

(c) \(₹\)
