Y = 10n + 500....after 20 weeks...n = 20
y = 10(20) + 500
y = 200 + 500
y = 700 <== she will have 700 songs at the end of 20 weeks

Answer: 2 1/2 cups of flour will make 1 Loaf of bread.
Step-by-step explanation:
3 loafs of bread can be made from 71/2 cups of flour
1 Loaf of bread will require = x cups of flour
By cross multiplication , we have
(1 Loaf of bread x 71/2 cups of flour) = 3 loafs of bread X x cups of flour
x cups of flour = (1 Loaf of bread x 71/2 cups of flour)/ 3 loafs of bread
=15/2 X 1/3 = 5/2 = 2 1/2
OR
7.5 /3 =2.5 = 2 1/2 cups of flour
Your answer would be x=3y + 15
