Answer:
First one:
a discount of 15% and then 10% and then 15% off that amount
Step-by-step explanation:
15% discount means 100-15 = 85% is to be paid
10% discount means 100-10 = 90% is to be paid
25% discount means 100-25 = 75% is to be paid
Let X be the cost before discount
1st offer:
85% of 90% of 85% of X
(85/100) × (90/100) × (85/100) × X
= 0.65025X
2nd offer:
75% of X
(75/100) × X
= 0.75X
Since 0.65025 < 0.75,
Offer 1 is better
