Carla's order at Mcdonald's costs $7.50, but she has a coupon for $2.50. If she gets an additional 20% discount for being a senior citizen, how much does she pay for her order in dollars total?
Закази Карла дар McDonald's 7.50 доллар аст, аммо ӯ купони 2.50 доллар дорад. Агар ӯ барои буданаш ҳамчун шахси калонсол 20% иловагӣ тахфиф гирад, ӯ барои закази худ дар маҷмӯъ чанд доллар пардохт мекунад?
How much does Carla's order cost without the coupon? ** First subtract the coupon amount from the price of the food: $7.50 - $2.50 = $<<7.5-2.5=5.00>>5.00
How much does Carla pay after the discount? ** Then subtract 20% from 100% to find out what percentage of the reduced price Carla pays: 100% - 20% = 80%
How much does Carla pay in total? ** Now multiply the price after the coupon by the percentage Carla pays to find the final price: $5.00 * .8 = $<<5*.8=4.00>>4.00
