Answer: In 7 years, Ms Acosta will earn $37,734.7

Step-by-step explanation:

From the information given, we find the increase using exponential growth formula

A= P(1+r)^t

Where p= the starting amount on the contract, given as $34000

r = rate, given at 1.5% = 1.5/100 = 0.015

t = time, given as 7years

Plug the values into the formula:

A = 34000(1 + 0.015) ^7

= 34000 (1.015)^7

34000 x 1.1098

A= $37,734.7

In 7 years, Ms Acosta will earn $37,734.7.

A group of friends wants to go to the amusement park. They have no more than $65 to spend on parking and admission. Parking is $
Aloiza [94]

Considering the definition of an inequality, the number of people who can go to the amusement park is 3.

<h3>Definition of inequality</h3>

An inequality is the existing inequality between two algebraic expressions, connected through the signs:

  • greater than >.
  • less than <.
  • less than or equal to ≤.
  • greater than or equal to ≥.

An inequality contains one or more unknown values ​​called unknowns, in addition to certain known data.

Solving an inequality consists of finding all the values ​​of the unknown for which the inequality relation holds.

<h3>Number of people who can go to the amusement park</h3>

In this case, you know that:

  • A group of friends has no more than $65 to spend on parking and admission.
  • Parking is $9.75, and tickets cost $16.25 per person, including tax.

Being "p" the number of people who can go to the amusement park, the inequality that expresses the previous relationship is

$9.75 + $16.25×p ≤$65

Solving:

$16.25×p ≤$65 - $9.75

$16.25×p ≤$55.25

p ≤$55.25÷ $16.25

<u><em>p≤ 3.4</em></u>

Finally, the number of people who can go to the amusement park is 3.
