Dave has $11 and he buys a book for $8 but he spends an equal amount of money on 2 cards. Let's model this problem with an inequality.
x = $ spent on one card.
2x + $8 ≤ $11
Let's subtract $8 from both sides.
2x ≤ $3
Divide both sides by 2
x ≤ $1.5
Dave can spend at most $1.5 on each card.
89% as a fraction would be 89/100 since it can not be reduced
So it gives you the answer for the first one
1 and 5 for the first box because it says he visited 5 in his first month
Then it says he visited 2 more each following month meaning each time it’s going to go up 2
So the box should look like
1-5
2-7
3-9
Then we have to figure out what goes in the x when y equals 23
So you can just go up by each month until one reaches 23 and it will be 10
So the final part of the box should say
10-23
The amount of parks is proportional to the amount of months.
What you have to do is multiply 5.12*2
10.24 meters
