Answer:
D
Step-by-step explanation:
We can rule out the second and third because the y intercept in those graphs are not 1
Now lets look at the point 2,5 on graph a
y=1/2x+1
so 5=1+1 but that is false
D is the answer by elimination
3 letters to US = 3*0.94 = 2.82
2 local letters = 2*0.44 = 0.88
checking: 2.82+0.88 = 3.70
to get rid out of 0.04 cents you have to multiply it by 5. so total number of letters would be 5.
1) 3+2+15=20
2) 3/4= 27/36 1/9=4/36
3) 27/36+4/36=31/36
4) 26/27=936/972 31/36= 637/972
5) 936/972 + 637/972= 1573/972= 1 601/972
