I. INTRODUCTION

Since it has been our task to look for new suppliers that will provide lower wholesale or retail price of rice, we canvassed two suppliers selling rice in wholesale and retail. But first of all why are the prices of rice necessary for us to know? I believe that the one reason we need to know the prices of rice is that we Filipinos eat rice every day of our lives. We all now that rice is very staple for us Filipinos and every year the prices of the rice increases due to economic crisis and affects the Philippines economy

That’s why we choose to canvas rice to compare which store is cheaper

II. PRESENTATION OF DATA

A. Price Table

Brand of Rice: Good Luck Rice

Name of Establishment | Wholesale Price(Php per 50 kg) | Retail Price(Php per kilo) |

Monterey | 2500.00 | 55.00 |

Ramonted Store | 2560.00 | 55.00 |

B. Mathematical Model expressing the total cost as a function of the number of goods.

Retail:

Let x be the amount of rice in kilos and f(x) be the total cost.

Equation of the function:

Monterey: g(x)= P55(x), 0<x<50

Ramonted Store: f(x)= P55(x), 0<x<50

Wholesale:

Let x be the number of sacks of rice and f(x) be the total cost.

Equation of the function:

Ramonted Store: f(x)= P2560(x), x>0

Monterey: g(x)= P2500(x), x>0

C. Graph of the Function

Retail: Monterey g(x)=55x, 0<x<50

Ramonted Store f(x)=55x, 0<x<50

Wholesale: Monterey g(x)= 2500x, x>1 (Blue Line)

Ramonted Store f(x)= 2560x, x>1 (Red Line)

III. INTERPRETATION AND RECOMMENDATION

A. Interpretation

The price table shows that the price of rice per kilos in Monterey and Ramonted Store is 55php. The Graph for retail shows that x can not be greater than 50kilos and less than...
