You must have the DENSITY of the material of which the object is made.
60 = .70 t Divide both sides by .7
60/.7 = t = 85.714
OR, if this is what you meant:
60 = .70^t Take the log of both sides
log60 = log(.70^t)
log60 = t log.70
t = log60/log.70 = -11.4792
190 x .20 = 38 SEK increase
New price = 190 + 38 = 228 SEK

Chris messed up between steps one and two
Step two SHOULD be:
-40 -75 +100 +200
-115 + 300
185
I do not know what you want.......you cannot solve for 'x' in this expression until you have an '=' sign to make it an equation.... Did you forget something?
1 job = 6 workers x 8days = 48 worker-days to get the job done
4 workers * 'x' days = 48 worker-days ?
48 worker-days / 4 workers = 12 days to get the job done.
PV = nRT
Where n is the number of moles of the number of moles and R is a constant called the universal gas constant and is equal to approximately 0.0821 L-atm / mole-K.
1.7 * 1.5 = n (.0821) (24+273.15)
n = (1.7 *1.5) / ((.0821 * (24+273.15))
= 2.55/24.396
n= .10452 moles
Can you tell us your problem?
