Answer:

The adult ticket costs $18 and the children ticket costs $13.

Step-by-step explanation:

Let the price of the adult ticket be a.

Let the price of the children ticket be c.

Three adults and four children must pay $106. This implies that:

3a + 4c = 106 _______(1)

Two adults and three children must pay $75. This implies that:

2a + 3c = 75 ________(2)

We have two simultaneous equations:

3a + 4c = 106 _____(1)

2a + 3c = 75 ______(2)

Multiply (1) by 2 and (2) by 3 and subtract (1) from (2):

  6a + 9c = 225

- <u>(6a + 8c = 212)</u>

             c = $13

Put this value of c in (2):

2a + 3*13 = 75

2a + 39 = 75

=> 2a = 75 - 39

2a = 36

a = 36/2 = $18

Therefore, the adult ticket costs $18 and the children ticket costs $13.

Suppose you had d dollars in your bank account. You spent $12 but have at least $51 left. How much money did you have initially?
PtichkaEL [24]

For this case we must raise an inequality.

We have "d" dollars initially and they are spent 12. Then:

d-12

At least 51 dollars remain, then, the sign of inequality is greater or equal in favor of the expressiond-12, that is:

d-12\geq 51

Resolving:

d\geq 51 + 12\\d\geq 63

There are at least 63 dollars left in the account.

Answer:

d-12\geq 51\\d\geq 63
