Answer:

(1)

Let the breadth be b , then length be 3b ,

Perimeter = 2(l+b)

36 = 2(b+3b)

36 = 8b

b = 36/8 = 4.5cm

l = 4.5 x 3 = 13.5cm

(2)

Let after X weeks they have same money , then

435 + 25X = 875 - 15X

40X = 875-435 = 440

X = 440/40 = 11

So , after 11 weeks , they will have same money

(3)

Not sure about dimes .

(4)

Weight of 50 cans = 312

Weight of a can = 312/50

Weight of 70 cans = 312/50 x 70

= 436.8 pounds

(5)

Total members = 18

Let she buys P t-shirts , and (18 - P) sweatshirts

According to question ,

9P + 15(18-P) = 180

9P +270 - 15P = 180

15P - 9P = 270 - 180

6P = 90

P = 90/6 = 15

So , number of t-shirts are 15 and number of sweatshirts are 18-15 = 3 .

Hope this helps ,
