Jo makes 170 minutes call. There are 150 free ones
170 - 150 = 20
20 minutes are "what Jo has to pay"
Jo sends 182 texts. There are 150 free ones
182 - 150 = 32
32 texts are "what Jo has to pay"
Monthly charge = 16p, 13p for each extra minute, 15p for each extra text.
13(20) = 260p
15(32) = 480p
480p + 260p + 16 = 740p + 16
740p + 16 is your answer (if p = pounds, add 16 to it, i'm not sure what p stands for though. If it is cents, divide 100 from 740 and take out the p, then add total to 16 to get answer.)
hope this helps

Answer:
Step-by-step explanation:
I understand why this was kind tough
the slope of line d is infinite and the slope of line c is zero
so line c 's equation looks like y = 3 ... it's kinda confusing but the line is always 3 so you could pick any x value and y = 3 still. the equation y=3 doesn't rely on x at all to answer it. But x is part of the "frame work" that is implied.
line d is x = 3 , again , y is part of the "frame work" and implied that y doesn't matter in this equations, you always have x = 3 .. or a vertical line , btw. line d does NOT pass the vertical line test , and therefore isn't a function, so the question is wrong, that d will have an equation, b/c there is an implication that d is a function when you say "what is the equation to line d" that is must be a function. But in this case it's not. hm :/ food for thought
Answer:
see explanation below
Step-by-step explanation:
1) 2011 sum
(6+8)100
14(100) = 1400 coins collected
2) 2015 difference
(6-4)100
2(100) = 200 coin difference
3) Henry is red. just look at the points where red is ABOVE blue
2011, 2014, 2015
4) you can take your answer from one and add it to the coins collected in 2010
1400 + (4+8)100
1400 + (12)100
1400 + 1200
2600 coins
5) Chris is in blue. just look at the points where blue is ABOVE red
3 years
but it asks months
so 3*12 and you get 36 months
