Answer:

Jenny 1.75 miles, Keith 4.75 miles, Jonna 9.5 miles

Step-by-step explanation:

Distance per person:

Jenny - x, Keith - y, Joanna - z

Equation as per given:

y = x + 3
z = 2y = 2(x + 3)
x + y + z = 16

Substitute and solve for x:

x + (x + 3) + 2(x + 3) = 16
2x + 3 + 2x + 6 = 16
4x = 7
x = 7/4 = 1.75

Then

y = 1.75 + 3 = 4.75
z = 4.75*2 = 9.5

Plz help for financial algebra

serious [3.7K]

Answer: $277.91

Step-by-step explanation:

The average of the 2 highest salaried quarters is:

$\dfrac{\$13,500+\$12,775}{2}=\dfrac{\$26,275}{2}=\$3,137.50$

Divide that by 26 (weeks) to find out her average weekly salary:

$\dfrac{\$3,137.50}{26}=\$505.29$

Multiply that by 55% (0.55) to calculate her weekly unemployment benefit:

$\$505.29(0.55)=\$277.908$

Round to the nearest penny --> $277.91
