Answer:
- Abel is 7 and Asare is 17 years old
Step-by-step explanation:
Let the age of Abel is x and age of Asare is y.
Three times the age of Abel is four more than the age of Asare:
And
In three years, the sum of their ages will be 30 years:
We got two equations.
Simplify and solve by substitution:
- 3x - 4 + x = 24 Substitute y
- 4x - 4 = 24
- 4x = 28
- x = 7
Find y:
One simple approach would be to choose an x value, such as x = 8, calculate y using the given formula, and then choosing the graph that shows a C(t) value closer to your calculated value.
Please evaluate C(8).
