Answer:
W(t) = 10 + 1.5*t
Step-by-step explanation:
Given:
The weight gain of the baby is 1.5 pounds per month.
After 4 months, baby's weight = 16 pounds
Let us the say the weight of the baby when it was born be x.
Then:
x + 1.5*(4) = 16
x = 10
Then weight of the baby as a function of number of months(t) will be=
initial weight + incremental weight per month*no of months(t).
W(t) = 10 + 1.5*t
Answer: 1.08t and (1+8/100)

Answer: 276 guests were at the wedding.
Step-by-step explanation:
Let x represent the number of guests that were at the wedding.
The guests had to choose their meal from beef,chicken or vegetarian.
1/3 of the guests chose beef. This means that the number of guests that chose beef is x/3.
If 5/12 of the guests chose chicken, it means that the number of guests that chose chicken is 5x/12. The total number of guests that chose beef and chicken is
x/3 + 5x/12 = 9x/12
The number of guests that chose vegetarian is
x - 9x/12 = 3x/12
69 of the guests chose vegetarian. This means that
3x/12 = 69
3x = 12 × 69 = 828
x = 828/3
x = 276 guests
