One winter week a ski town got 15 1/2 inches of snow. on monday the town got 2 3/4; on tuesday it got 1 1/2 times as much; and on wednesday it got 7/8 inch. how much snow did the town get the rest of the week.

Total one winter week snow fall = 15 1/2 inches .

On Monday it's =  2 3/4 inches.

On Tuesday = 1 1/2 times of 2 3/4 inches = 3/2 × 11/4 = 33/8 = 4 1/8 inches.

On Wednesday = 7/8 inches.

Total snow fall on Monday, Tuesday and Wednesday = 2 3/4 inches + 4 1/8 inches +  7/8 inches

= 6 + 3/4 + 1/8 +7/8 = 6 + 6/8 + 1/8 +7/8

= 6 + 14/8 = 6 + 1  6/8 = 7 6/8 or 7 3/4 inches.

In rest of the week the snow fall is = 15 1/2 inches - 7 3/4 inches.

8 inches + (1/2 - 3/4 ) = 8 inches + (2/4 - 3/4 )

8  - 1/4 = 8/1 -1/4

= 32/4 - 1/4

= 31 /4

= 7 3/4 inches.

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
