Ravi has some money. If he buys 40 doughnuts, he will have $5 left. If he buys 50 doughnuts,he will need another $15. How much d

anastassius [24]

Difference in doughnuts = 50 - 40 = 10
Difference in money = 15 + 5 = 20

20 ÷ 10 = $2
Each doughnut costs $2

<em>Check:</em>
40 x 2 + 5 = $85
50 x 2 -15 = $85
Ravi has $85 at first.

Each doughnut costs $2

A taxi company charges $1.00 for the first mile (or part of a mile) and 20 cents for each succeeding tenth of a mile (or part).

meriva

Step-by-step explanation:

solving functions separately.

1st: from given data taxi charges $1.00 for the first mile.so it is first rule of function.

$y_{1} =1 , 0$

2nd: the company charge $0.20 per tenth of a mile.so 2nd rule of the function will be

$y_{2} =1+0.2.10(x-1)$

simplifying

$y_{2} =1+2(x-1)$

$y_{2} =x+2x-2$

$y_{2} =x$ , $1$

piece wise function is f(x)={2 , 0<x<1

{x , 1<x<2

the graph of the function is given below
