Chen is bringing fruit and veggies to serve at an afternoon meeting. He spends a total of $28.70 on 5 pints of cut veggies and 7
ololo11 [35]
Given:
total cost : 28.70
cost per pint of fruit : 2.85

Formula: 
5v + 7f = 28.70
5v + 7(2.85) = 28.70
5v + 19.95 = 28.70
5v = 28.70 - 19.95
5v = 8.75
5v/5 = 8.75/5

v = 1.75  cost per pint of veggies.

to check:
v = 1.75 ; f = 2.85 ; total cost = 28.70

5v + 7f = 28.70
5(1.75) + 7(2.85) = 28.70
8.75 + 19.95 = 28.70
28.70 = 28.70

A certain forest covers an area of 1900km^2. Suppose that each year this area decreases by 7.75%. What will the area be after 14
yarga [219]

Answer:

Assume that 1900km^2 is 1900.

If that happens, The equation of that will look like...

1900 - (1900 x 7.75% x 14)%.

1900 x 7.75% are 147.25.

and 147.25 x 14 are 2061.5.

so... there will be no forest after 14 years.(harsh)

Hope it helps!
