Answer 1

is this the inequality equation 3r+24 <= 100?

Answer 2

that sounds good because
1 rewarding we have 3+the already 24
2 rewardings we have 6+the already 24
3r+24 looks good
now they need a 100 or more the have that party right?
so correct me if I'm wrong shouldn't the inequality be 3r+24>=100

Answer 3

yes that makes sense

Answer 4

so the next equation
if we want a single party then 3r+24=100

if we wanted two parties we would have 3r+24=200
if we wanted three parties we would have 3r+24=300

Answer 5

and by the way it is only asking for a single party not more

Answer 6

so 3r+24=100
means r=?

Answer 7

you are going to have to round that r to a certain whole number

Answer 8

since it says whole number of times

Answer 9

well 3r=76
and r=?

Answer 10

3

Answer 11

3r=76

to solve for r you to divide both sides by 3

Answer 12

r=76/3 approximately 25.333

what whole number do you think we need to round this to?
remember we want to find the whole number of times of rewardings so that we can get a total of 100 to have a single party

Answer 13

you have really only two choices
do we need 25 rewardings or 26 rewardings to get the min of 100 marbles to have the single party?

Answer 14

let's think about it
if r=25 then 3(25)+24=?

Answer 15

99

Answer 16

is 99 enough?

Answer 17

no

Answer 18

so it looks like we need r to be 26
we might have a little more than 100
but we will have at least 100

Answer 19

if r=26, then 3(26)+24=78+24=102

Answer 20

102 is a little more than enough right?

Answer 21

yes

Answer 22

but the class will have to be rewarded 26 times to even reach the 100 or more marker

Answer 23

does that make sense?

Answer 24

yes

Answer 25

do you have any questions?

Answer 26

not now, thank you :)
