Achemical manufacturer has two purchasing plans available for a certain liquid chemical. plan a is one dollar per gallon plus an an annual fee of 50 dollars. plan b is 50 cents a gallon plus an annual fee of 100 dollars. specify the condition for which plan a is a better deal than plan b.

Let the number of gallons = g

First plan is

Plan A is one dollar per gallon plus an an annual fee of 50 dollars, that is

Second plan is

Plan B is 50 cents a gallon plus an annual fee of 100 dollars.

For plan A better than plan B,

It means, numer of gallons must be less than 100 .

-4

step-by-step explanation:

(-4+8)=-(4-8)=-8+4=-4

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30
