Explain witch situation will give you the best price : a discount of 15% and then 10% and then 15% off that amount ,or a discount of 25%

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

80%

step-by-step explanation:

answer: 1,380

step-by-step explanation:

1: you turn %15 into a decimal by moving the decimal point two places to the left.

2: and then you multiply .15 by 1,200 , which will get you 180.00

3: from there you will add 180 to 1,200

4: which will get you 1,380
