Paul, colin and brian are waiters. one night the restaurant earns tips totalling £78.40. they share the tips in the ratio 2: 1: 5. how much more does brian get over colin? how much more does colin get over brian

Step-by-step explanation:

The total of ratio units is 2+1+5 = 8. Brian gets 5 and Colin gets 1, so Brian gets (5-1) = 4 ratio units over Colin. Of the total tips, that is 4 of 8 ratio units or 4/8 = 1/2 of the tips:

  Brian over Colin = (1/2)(£78.40) = £39.20

The amount Colin gets over Brian is the opposite of this: -£39.20.

answer: the equation matches the regression
