Answer:
Amount left = 2040
Step-by-step explanation:
Given that:
Per year salary = 12,000
Amount spent on transport = 10%
Transport = = 0.1 * 12000
Transport = 1200
Tax = 5%
Tax = 0.05 * 12000
Tax = 600
Total = 1200 + 600 = 1800
Amount left = 12000 - 1800 = 10200
Food = 80% of remainder
Food = 0.8 * 10200
Food = 8160
Amount left after food = 10200 - 8160 = 2040
Hence,
2/5 (x-1)=15 (x=7)
7 (1+3m)=49 (m=2)
Multiply the money * the hours
5*7= 35
Answer : $35
$325
Let the dryer price be x, then the washer price would be x-78
x+x-78 = 572
2x = 650
x = 325
