Answer:
Price at issuance is $1,000 for both bonds.
Price of the 5 year bond after the market rate increased to 7.4% is:
PV of face value = $1,000 / (1 + 3.7%)⁸ = $747.77
PV of coupon payments = $27.50 x 6.81694 (PV annuity factor, 3.7%, 8 periods) = $187.47
Market price = $935.24
this bond's price decreased by 64.76/1,000 = 0.06476 = 6.48%
Price of the 10 year bond after the market rate increased to 7.4% is:
PV of face value = $1,000 / (1 + 3.7%)¹⁸ = $519.97
PV of coupon payments = $27.50 x 12.97365 (PV annuity factor, 3.7%, 18 periods) = $356.78
Market price = $876.75
this bond's price decreased by 123.25/1,000 = 0.12325 = 12.33%

Answer:
A variety of factors affect development, prenatally and postnatally. A non-biological factor, the drug use by parents before and after child´s birth, affect both.
Explanation:
Drug use before, during and after pregnacy problem outcomes form, both individual and environmental reasons. Drug prevention and treatment, traditionally focused on changing individual behaviours have had very limited impact
, as the environment hasn´t had necessary change, and the social determinants of drug use have increased, with exacerbating factors that include cognitive limitations, poor parenting and low family socio-economic status, causing the development of children, not receiving the nutrition and stimulation necessary, to be significantly impeded since the very conception, causing genetic predisposition to drug use; in neonatal and infancy, the consequence might be to get a child with difficult temperament
, in preschool, children could develop early behavioural and emotional disturbances, such as oppositional defiant disorder or, depression
; in primary school, children could be unable to self-regulate emotions and behaviour
; if they get to high school, children may be exposed to drug-using social contexts.
