Answer:
90
Step-by-step explanation:
Rewriting what is given: (0.09)(n)=30
Where n is the unknown number and 0.09 is the numerical form of 9%. Solving for n gives:
n=(30/0.09)=333.333....
27% as a number is 0.27. So 27% of n is:
(0.27)(n)=(0.27)(333.333...)=90
27% of that number is 90.

1) 3j + 5p = 7.60 and 1j + 2p = 2.90
2) Solving for j and p
j = 2.90 - 2p
3(2.90 - 2p) + 5p = 7.60
8.7 - 6p + 5p = 7.60
8.7 - p = 7.60
-p = -1.1
p = 1.1
1j + 2(1.1) = 2.9
j + 2.2 = 2.9
j = .7
3) The values of p and q:
p = $1.1 per pancake, j = .70 cents per glass
