Final answer:
Deal A gives the best price for Jamie's new phone and personalized phone case purchase, with a total cost of £202.70, compared to Deal B's total cost of £207.25.
Step-by-step explanation:
Which deal would give the best price for Jamie's purchase?
To determine which deal gives the best price for Jamie's new phone and personalized phone case purchase, let's calculate the total cost under both Deal A and Deal B.
Deal A offers a 65% discount on accessories when buying a phone. Therefore, the discount on the personalized phone case (£22) would be:
65% of £22 = 0.65 × £22 = £14.30.
The discounted price of the case would then be:
£22 - £14.30 = £7.70.
Total cost under Deal A (phone + discounted case):
£195 + £7.70 = £202.70.
Deal B offers a 5% discount on the phone. Therefore, the discount on the phone (£195) would be:
5% of £195 = 0.05 × £195 = £9.75.
The discounted price of the phone would then be:
£195 - £9.75 = £185.25.
Total cost under Deal B (discounted phone + full price case):
£185.25 + £22 = £207.25.
Comparing the total costs of both deals, Deal A offers a lower total cost at £202.70, versus Deal B at £207.25.
Therefore, Deal A gives the best price.
