The price of a math textbook in the school bookshop is $45. If those sold in bookshops outside the school cost 20% less, how much can Peter save by buying from other bookshops rather than the school's if he wants to buy 3 math textbooks?
Нархи китоби математика дар дӯкони китобфурӯшии мактаб $45 аст. Агар онҳое, ки дар дӯконҳои китобфурӯшии берун аз мактаб фурӯхта мешаванд, 20% арзонтар бошанд, Питер чӣ қадар пулро бо харидани китобҳо аз дӯконҳои дигар, на дӯкони мактаб, сарфа мекунад, агар ӯ хост 3 китоби математика харидорӣ кунад?
How much does a math textbook cost in a bookshop outside the school? ** 20% of $45 is (20/100)*$45 = $<<(20/100)*45=9>>9
How much does a math textbook cost in other bookshks? ** The price of the textbook in other bookshops cost $9 less than $45 which is $45-$9 = $<<45-9=36>>36
How much would three textbooks from the school bookshop cost? ** Three textbooks from the school bookshop would cost $45*3 = $<<45*3=135>>135
How much would three textbooks from another bookshop cost? ** Three textbooks from another bookshop would cost $36*3 = $<<36*3=108>>108
How much can Peter save by buying from other bookshops rather than the school's if he wants to buy 3 math textbooks? ** Peter can save $135-$108 = $<<135-108=27>>27 by buying from another bookshop

Чанд пулӣ арзиши китобҳои математика дар китобфурӯшии берун аз мактаб аст? ** 20% аз $45 ин (20/100)*$45 = $<<(20/100)*45=9>>9  
Чанд пулӣ арзиши китобҳои математика дар китобфурӯшии дигар аст? ** Арзиши китоб дар китобфурӯшии дигар $9 камтар аз $45 аст, ки $45-$9 = $<<45-9=36>>36  
Чанд пулӣ арзиши се китоб аз китобфурӯшии мактабӣ хоҳад буд? ** Се китоб аз китобфурӯшии мактабӣ $45*3 = $<<45*3=135>>135 хоҳад буд  
Чанд пулӣ арзиши се китоб аз китобфурӯшии дигар хоҳад буд? ** Се китоб аз китобфурӯшии дигар $36*3 = $<<36*3=108>>108 хоҳад буд  
Чанд пулӣ Питер метавонад бо харидани китобҳо аз китобфурӯшии дигар, на аз китобфурӯшии мактабӣ, сарфа кунад, агар ӯ мехоҳад 3 китобҳои математика бихарад? ** Питер метавонад $135-$108 = $<<135-108=27>>27 бо харидани китобҳо аз китобфурӯшии дигар сарфа кунад
