Each week he earns $142.5 from his partime job plus $25 from chores and then saves 85% of that total ($167.5). 85x167.5 = 14237.5 divided by 100 = 142.375 which is 85% of what he earns each week. Then multiply that by 8 weeks to find his total on August 25th. The answer should be $1,139

Step-by-step explanation:
(3 x 10) + (2 x 6)
30+12=42
Cuando has simplificado la ecuación lo mas posible y las expresiones de los dos lados quedan iguales, hay soluciones infinitas. Pero, dado que lo has simplificado y son diferentes, no hay solución.
1.) 7x = 12 + 7x - 12
=> 7x = 7x => infinita solución
2.) x - 11 = 11 + x
=> x = 22 + x => no solución
3.) 2(4x - 6) = 8(x + 2)
=> 8x - 12 = 8x + 16 => 8x = 8x + 28 => no solución
4.) 2x - 9 = 2x - 9
=> infinita solución
5.) 8 + 4x = 4x + 10
=> 4x = 4x - 2 => no solución
