Urgent help!
Alchen [17]

Answer:

(i) 80-x

(ii) S(x) = 40 - 0.10x

(iii) $36.5

Step-by-step explanation:

Given that:

1. Total Number of fruits = 80

2. Number of mangoes = x

3. Both mangoes and oranges are there in the basket.

Solution (i):

Only mangoes and oranges are there in the basket and the basket is full.

so, Number of mangoes + Number of oranges = Total number of fruits

x + Number of oranges = 80

Number of oranges = 80 -x

Solution (ii):

<u>Given:</u>

Cost of an orange = 50 cents = $0.50

Cost of a mango = 40 cents = $0.40

Cost for x mangoes = \$ 0.40x

Cost for (80-x) oranges = \$ 0.50 \times (80-x)

\Rightarrow S(x) = 0.50 (80-x) + 0.40x\\\Rightarrow S(x) = 40 -0.50x + 0.40x\\\Rightarrow S(x) = 40 - 0.10x

Solution (iii):

Put value of x = 35 in S(x)

S(35) = 40 - 0.10 (35)\\\Rightarrow S(35) = 40 - 0.35\\\Rightarrow S(35) =\$ 36.5

Hence, answers are:

(i) 80-x

(ii) S(x) = 40 - 0.10x

(iii) $36.5
