1.
shop A: 1 - (1248 / 1920 *100%) = 35%
shop A offers 35% off
shop B: 1 - (1320 / 1760 *100%) = 25%
shop B offers 25% off
Therefore, shop A offers a larger discount.
2.
New price of watch = $200 * (1-20%) = $160
New price of pen = $180 * (1-15%) = $153
Therefore, total price = $160 + $153 = $313
shop A: 1 - (1248 / 1920 *100%) = 35%
shop A offers 35% off
shop B: 1 - (1320 / 1760 *100%) = 25%
shop B offers 25% off
Therefore, shop A offers a larger discount.
2.
New price of watch = $200 * (1-20%) = $160
New price of pen = $180 * (1-15%) = $153
Therefore, total price = $160 + $153 = $313

1.
In shop A, the discount = 1 - ($1248/ $1920) = 1 - 0.65 = 35% discount
In shop B, the discount = 1 - ($1320/ $1760) = 1 - 0.75 = 25% discount
Therefore, Shop A offer a larger discount than Shop B.
2.
The total should pay = $200 * (1-20%) + $180 * (1-15%) = $160 + $153 = $313
In shop A, the discount = 1 - ($1248/ $1920) = 1 - 0.65 = 35% discount
In shop B, the discount = 1 - ($1320/ $1760) = 1 - 0.75 = 25% discount
Therefore, Shop A offer a larger discount than Shop B.
2.
The total should pay = $200 * (1-20%) + $180 * (1-15%) = $160 + $153 = $313
