Answer:
Step-by-step explanation:
Let y represent the number of yellow sweatshirts sold. Then the total revenue is ...
$11.95(25 -y) +$12.50(y) = $304.25
$0.55y +$298.75 = $304.25 . . . simplify
$0.55y = $5.50 . . . . . . subtract $298.75
y = 10 . . . . . . . . . . divide by $0.55
25-y = 15 . . . . the number of white sweatshirts sold
10 yellow and 15 white sweatshirts were sold.
Your only option is to fill in the given points. That will give you two equations from which you can work out k and a.
Fill in (1,7) gives the easy formula 7 = k·a
Fill in (3,175) gives 175 = k·a·a·a
If you replace k·a in the second one with 7, you get:
175 = 7·a·a => a²=25 => a=5
Fron this and the first eqn follows k=7/5
