Answer:
P = 225 P profit on 20 kilos of mangoes
Values:
Mangoes sold: [tex]20*7=140\\[/tex]
Cost paid for each mango: [tex]\frac{50}{7}[/tex]
Price each melon sold for: [tex]\frac{35}{4}[/tex]
Step-by-step explanation:
1. Substitute given values; [tex]P = 140(\frac{35}{4} - \frac{50}{7})[/tex]
2. Find common denominator: [tex]P=140(\frac{245}{28}-\frac{200}{28} )[/tex]
3. Subtract equation in parentheses: [tex]P=140(\frac{45}{28} )\\[/tex]
4. Divide [tex]140\\[/tex] by [tex]28[/tex] to remove denominator; [tex]P=5(45)[/tex]
5. Solve equation: [tex]P=225[/tex]
