Anna35 [415]

Answer:

(a) $Y = \frac{2}{7} X+\frac{500}{7}$

(b) Here the intercept means that we pay $\frac{500}{7}$ more than $\frac{2}{7} X$ for each text message received

(c) 145 text messages sent and 30 messages received

75 text messages sent and 50 messages received

180 text messages sent and 20 messages received

Step-by-step explanation:

Here we have

X×0.02 + Y×0.07 = 5

Therefore the equation is

$Y = \frac{2}{7} X+\frac{500}{7}$

b. Here the intercept means that we pay $\frac{500}{7}$ more than $\frac{2}{7} X$ for each text message received

c. Other combinations are

145 text messages sent and 30 messages received

75 text messages sent and 50 messages received

180 text messages sent and 20 messages received.
