We have;
- I have $30, given by mom for shopping
- Cost of one candy bar = $2
- Cost of one chips pack = $3
We need to make 2 possible combinations and yeah, we are free to buy the quantities of two of them, so umm.. let's suppose;
- 6 packs of chip = 6 × 3 = $18
- 6 candy bars = 6 × 2 = $12
And for the next;
- 4 packs of chip = 4 × 3 = $12
- 9 candy bars = 9 × 2 = $18
And for the two ordered pair let candy bars be x and chips be y; so there pair must be, (12,18) & (18,12)
