Rose bought green mangoes at P50 a kilo and sold them at 4 for P35. If she sold 20 kilos and there is an average of 7 mangoes per kilo, about how much did she gain?

Respuesta :

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]
