Answer:
<u>The number of copies that will make it worth the discount card is 250.</u>
Step-by-step explanation:
1. Let's review the information provided to answer the question correctly:
Cost per copy without discount = US$ 0.08
Cost per copy with discount = US$ 0.05
Cost of discount card = US$ 7.50
2. How many copies will make it worth the discount card?
For finding out this number of copies, we will use the following equation:
x = Number of copies that will make it worth the discount card
0.08x = 0.05x + 7.50
0.03x = 7.50 (Like terms)
3x = 750 (Multiplying by 100 at both sides)
x = 250 (Dividing by 3 at both sides)
<u>The number of copies that will make it worth the discount card is 250.</u>

Answer:
y=15
Step-by-step explanation:
Because of the exterior angle theorem angle A plus angle b or equal to 146.
so you set 5y+3+4y+8=146 and solve
5y+3+4y+8=146
9y+11=146
9y=135
y=15
Answer:
The most tickets were written on Saturday .On Saturday 325 tickets were issued
Step-by-step explanation:
The average number of traffic tickets issued in a city on any given day Sunday-Saturday can be approximated by
Where x represents the number of days after Sunday
T(x) represents the number of traffic tickets issued.
Sunday = x=0
Monday = x=1
Tuesday = x=2
Wednesday = x=3
Thursday = x =4
Friday = x=5
Saturday = x=6
Substitute x= 0
On Sunday 37 tickets were issued
Substitute x= 1
On Monday 115 tickets were issued
Substitute x= 2
On Tuesday 181 tickets were issued
Substitute x= 3
On Wednesday 235 tickets were issued
Substitute x= 4
On Thursday 277 tickets were issued
Substitute x= 5
On Friday 307 tickets were issued
Substitute x= 6
On Saturday 325 tickets were issued
Hence the most tickets were written on Saturday .On Saturday 325 tickets were issued
Answer:
B) y = 129º
Step-by-step explanation:
since a triangle is 180º in total, the you have to subtract 71 and 58 from 180 which will give you 51º which gives you the amount for x
and the line that the triangle is on is also 180º in total, so you subtract the 51 from 180 to give you a total of 129º which is the amount for y
All you have to do is divide 38 divided by 5 which = 7 r 3
I hope this helps.
Have a awesome day. :)
