Adoll house has 15.5 square feet downstairs and 6.25 square. feet upstairs. which of the following is the best estimate of the total area in the dollhouse? a. 9 square feet. b.21 square feet. c.78 square feet d. 90 square feet.

The correct answer is : B.21 square feet.

Step-by-step explanation:

A doll house has 15.5 square feet downstairs and 6.25 square feet upstairs.

The best estimate of the total area in the dollhouse will be = combined area of both the floors.

=> = 21.75 square feet

Therefore, the correct answer is option B = 21 square feet.

tickets for the harlem globetrotters

show at michigan state university in

2010 cost $16, $23, or, for vip seats, $40.

total revenue = 16x + 23y + 40z

if 9 times as many $16 tickets were sold

as vip tickets,

x = 9z => x – 9z = 0, if 9 times as many $16 tickets were sold

as vip tickets,

x = 9z => x – 9z = 0, sales of all three kinds of tickets would

total $46,575.

16x + 23y + 40z = 46575, how many of each kind of ticket would

have been sold?

solve for x, y and z

x − 9z = 0

x − y − z = 55

16x + 23y + 40z = 46575

x = 1170

y = 985

z = 130
