calculate the missing values.

for the six month period given, fred wants to calculate the monthly deviation from the average.

month sales average deviation
july $1,250 1,412.50 -162.50
aug. $1,700 1,412.50 ( )
sept. $1,125 1,412.50 ( )
oct. $1,850 1,412.50 ( )
nov. $1,500 1,412.50 ( )
dec. $1,050 1,412.50 ( )

Subtract the average from the sales to get the deviation.

Aug. 1700 - 1412.50 = 287.50

Sept. 1125 - 1412.50 = -287.50

Oct. 1850 - 1412.50 = 437.50

Nov. 1500 - 1412.50 = 87.50

Dec. 1050 - 1412.50 = -362.50

answer: your correct answer is b. d.

step-by-step explanation:

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2
