Your friend Michelle just graduated and has two job offers that she is considering. Both job offers pay the same, but JobA

just olya [345]

Money offered to Michelle per annum in Job A = $1700

Number of years she will work in job A = 5

Percentage of earnings per annum for her retirement plan = 6.60%

Money she will earn will be the simple interest at the end of 5 years.

We know that :

$\color{plum}{ \tt{Simple \: interest = \frac{Principle \ \: \times \: Rate \: \: \times \: \: Time}{100} }}$

Principal = $1700

Rate = 6.60%

Time = 5 years

Which means :

$= \frac{1700 \times 6.60 \times 5}{100}$

$= \frac{56100}{100}$

$= \color{plum}\$561$

We also know that :

$\color{plum}\tt \: Amount = Principal + Interest$

Amount Michelle will earn at the end of 5 years for her retirement plan :

$= 1700 + 561$

$=\color{plum}\bold{\$ 2261}$

2261 can be rounded off to 2260.

Therefore, Michelle will earn <u>$2260</u> at the end of 5 years for her retirement plan.

If the straight line passing through A(-7, -5) and B(-3, x) is parallel to another straight line of slope 2, find the value of x

Ostrovityanka [42]

X=3; you can set up a proportion using the slope equation. So (y[sub2]-y[sub1])/(x[sub2]-x[sub1])=2/1 then plug in the values and simplify. Then cross multiply and solve for x. Rest of work shown in the picture
