Question

Mrs Logan won some money for her classroom. She spent 3/7 of the money on technology for her classroom. She spent 2/5 of the remainder on books. Mrs logan then bought games for $125, manipulatives for $100.00 and treats for the class party for $75.00. If she spent all her money, how much money did mrs logan win?

Answer 1

X is the total amount

(3/7) X = (15/35)X on technology

(2/5)(4/7)X = (8/35)X on books

(12/35)X = 125+100+75

(12/35)x = 300

X = 300*35/12

= 875

started with 875

3/7*875 = 375 on technology...

500 remains..

8/35* 875 = 200 on books

300 remains...

final 300 spend on games,

manipulatives, and party supplies
