Ezra works two summer jobs to save for a laptop that costs at least $1100. He charges $15/hr to mow lawns and $10/hr to walk dog
LiRa [457]

\\
\text{Ezra works two summer jobs to save for a laptop that costs at least }\$1100\\
\\
\text{also given that he charges 15 dollars per hour to mow lawns and }\\
\text{10 dollars per hour to walk dogs.}\\
\\
\text{so if he mow lawns for x hours and walk the dogs for y hours in summer,}\\
\text{then the inequality that modeles this data is}\\
\\
15x+10 y \geq 1100

\text{now suppose Ezra decides to also spend more than }\$80 \text{ on a printer,}\\
\text{so the total expences he want for laptop and printer is}=1100+80=1180\\
\\
\text{so now the inequality becomes: }

15 x+10 y >1180

Alice placed $1,900 in a savings account which earns 2.2% interest, compounded every year. How much will she have in the account
ella [17]

She will have $2118 in her account after five years

<h3>How to determine the amount in five years?</h3>

The given parameters about the compound interest are

Principal Amount, P = $1,900

Interest Rate, R = 2.2%

Time, t = 5

Compound interests are different from simple interest, and they are calculated using the following compound interest formula

CI = P(1 + R)^t - P

To calculate the amount, we have:

A = P + CI

So, the equation becomes

A = P + P(1 + R)^t - P

Evaluate the like terms

A = P(1 + R)^t

Substitute the known values in the above equation

A = 1900 * (1 + 2.2%)^5

Express 2.2% as decimal

A = 1900 * (1 + 0.022)^5

Evaluate the sum

A = 1900 * (1.022)^5

Evaluate the exponent

A = 1900 * 1.11495

Evaluate the product

A = 2118

Hence, she will have $2118 in her account after five years

Julia used 1 foot square stone tiles to make a patio. She laid the tiles in a square, 7 tiles wide by 7 tiles long. What is the
marshall27 [118]

Answer: 49\ ft^2

Step-by-step explanation:

The formula that is used to calculate the area of a square is this one:

A=s^2

Where "s" is the side lenght of the square

You know that Julia used 1 foot square stone tiles, then each side lenght of the this tiles is:

s_{tile}=\sqrt{1\ ft^2}\\\\s_{tile}=1\ ft

Since Julia laid 7 tiles wide by 7 tiles long, the side lenght of the new patio is:

s_{patio}=7(1\ ft)\\\\s_{patio}=7\ ft

Therefore its area is:

A_{patio}=(7\ ft)^2\\\\A_{patio}=49\ ft^2
