The municipal swimming pool in Nicetown has three different ways of paying for individual open swimming. Todd is trying to decide which way to pay. • Early Pay: Pay $70 before Memorial Day; swim any number of days • Deposit Plus: $15 deposit plus $4.00 per day • Daily Pay: $6.00 per day
Answers
If x is the number of days and y is the cost
a) y = 0x + 70 or y = $70
If there is no daily cost, then the price will always remain $70. (Blue)
There will be a horizontal line intersecting the y axis at $70.
b) y = 4x + 15
The initial cost in addition to whatever the number of days is, multiplied by $4 per day.
Day 1: (4 x 1) + 15 = $19
Day 2: (4 x 2) + 15 = $23
Day 3: (4 x 3) + 15 = $27
Day 4: (4 x 4) + 15 = $31
By now, we should be able to notice a pattern, the y value always increases by $4, after starting at y = $19
On the graph, after plotting these 4 points, we would just continue the straight line along until it spreads across the entire graph.
c) y = 6x
The total cost for all the sessions will be the number of days multiplied by the cost per day.
As it is 6 multiplied by the number of days, we must write out the 6 times table:
x = 1 2 3 4 5 6 7 8 9 10
y = 6, 12, 18, 24, 30,36, 42, 48, 54, 60 etc.
Just plot some of these co-ordinates on the line (at least three to be sure) and check that they make a straight line. They are correct if they do.
After plotting all these co-ordinates, we will get something that looks like the image attached.
This tells us that daily pay is cheaper, until 8 days have passed. After that, it gets increasingly pricier to pay per day. Deposit plus then becomes the cheapest until the 14 day mark, where it then becomes cheaper to have paid the Early pay. From then onwards, early pay would have been the best option to choose.
Daily Pay - up to and including 7 days
Deposit Plus - up to and including 13 days
Early Pay - 14 days or more.

Answer:
She spent 29/35 of total amount she had.
Step-by-step explanation:
Let the amount Shalyn had be x.
She spent 2/5 of her money on a ticket. (i.e 2/5 of x)
She spent 3/7 of her money on popcorn. (i.e 3/7 of x)
So we need to find the total she spent.
i.e Total amount spent =Amount spent on movie ticket + amount spent on popcorn
Total amount spent = 2/5 of x + 3/7 of x
Total amount spent = (2/5 + 3/7 ) of x
Total amount spent = (29/35) of x
So she spent 23/35 of total amount she had.
