Tony sells biscuits at school for R15 per packet. He rents a small store at school for R200 per week and buys biscuits in bulk at a cost of R5 per packet. • He formulated Income and Expenses equations and drew graphs to assist him determine the break-even point for his business. •⚫ Expenses =R200 + 5 x n (where n represents the number of biscuits) • Income = R15 × n (where n represents the number of biscuits) ​

Answer:

20 packets of biscuits

Step-by-step explanation:

The expense formula is
E = 200 + 5n

The income formula is
I = 15n

The break-even point occurs when income = expenses:
I = E
15n = 200 + 5n

Subtract 5n from both sides:
15n - 5n = 200
10n = 200
n = 200/10

= 20 packets of biscuits
