Answer:

Mariah bought 4 pounds of lime ans 5 pounds of pears.

Step-by-step explanation:

Let l be the number of pounds of limes.

Let p be the number of pounds of pears.

Mariah spent $9.50 on 9 pounds of limes and pears.

l+p=9 or l=9-p    .....(1)

Limes cost $0.50 per pound and pears cost $1.50 per pound.

0.5l+1.5p=9.50    ....(2)

Putting l-9-p in (2)

0.5(9-p)+1.5p=9.50

4.5-0.5p+1.5p=9.50

1p=5

So, p = 5

And l=9-p

l=9-5=4

l= 4

So, Mariah bought 4 pounds of lime ans 5 pounds of pears.

Resale Value Garland Mills purchased a certain piece of machinery 2 years ago for $500,000. Its present resale value is $420,000
Natasha2012 [34]

Answer:

260,000

Step-by-step explanation:

The value decreases by 40,000 per year (500000-42000/2 years) the value will decrease by 240000 in six (4 years plus 2 years already passed) years. 6 x 40,000 =240000

So, the value should be 260,000 (500000-240000)

Or

year 1 500000-40000=460000

year 2 460000-40000=420000

year 3 420000-40000=380000

year 4 380000-40000=340000

year 5 340000-40000=300000

year 6 300000-40000=260000
