 
 <prompt> Madam Snyder dey spend 40% of her monthly income on rent and utilities before. Dem increase her salary by $600 so now her rent and utilities na only 25% of her monthly income. How much be her previous monthly income? <response>: ```Make we assume say her previous monthly income na p
The cost of her rent and utilities na 40% of p wey be (40/100)*p = 2p/5
Her income don increase by $600 so e be now p+$600
The cost of her rent and utilities now na 25% of (p+$600) wey be (25/100)*(p+$600) = (p+$600)/4
If we equalize both expressions for cost of rent and utilities: 2p/5 = (p+$600)/4
If we multiply both sides of the equation by 20, we go get 8p = 5p+$3000
If we subtract 5p from both sides, we go get: 3p = $3000
If we divide both sides by 3, we go get p = $1000

The answer go be 1000.```
