TEA [102]

Kira has 22 cards, Randall has 44 cards, and Sean has 34 cards

<u>Solution:</u>

Given that, Randall, Kira and Sean have 100 baseball cards altogether.

Randall has twice as many as Kira and 10 more than Sean.

We have to find how many baseball cards does each person have?

Now, let the number of cards with Kira be "n", then number of cards with Randall will be "2n"

As Randall has "2n" cards, Sean will have 2n – 10

Now, total cards = 100

<em>Randall cards + Kira cards + Sean cards = 100 </em>

2n + n + 2n – 10 = 100

5n = 100 + 10

5n = 110

n = 22

So, kira has 22 cards, then, randall will have 2(22) = 44 cards and cards with sean = 44 – 10 = 34 cards.

Hence, kira has 22 cards, randall has 44 cards, and sean has 34 cards.

<h3><u>An inequality to show how much he might spend on souvenirs and snacks is:</u></h3>

$x\leq 13.5$

<h3><u>Solution:</u></h3>

Given that,

Gabe went to the amusement park with $40 to spend

His ticket cost $26.50

Therefore,

Total amount she has = $ 40

Ticket cost = $ 26.50

Let "x" be the amount he might spend on souvenirs and snacks

Therefore,

Remaining amount = 40 - 26.50

Remaining amount = 13.5

Thus she can spend less than or equal to $ 13.5 on souvenirs and snacks

Which is represented in inequality as:

$x\leq 13.5$

Thus the inequality is found
