Answer:
The answer to your question is 7 large and 16 small
Step-by-step explanation:
Data
cost large frame = $13
cost small frame = $5
total number of frames = 23
total cost = $171
large frame = l
small frame = s
Process
- Write equations that help to solve the problem
l + s = 23 Equation l
13l + 5s = 171 Equation ll
-Multiply equation l by -5
-5l - 5s = -115
13l + 5s = 171
8l + 0 = 56
8l = 56
l = 56/8
l = 7
-Find s
7 + s = 23
s = 23 - 7
s = 16
-Conclusion
She bought 7 large frames and 16 small frames.
X = 25
Y = 10.8
All I did is divide 30 by 50 which is .6 then I multiple by 18 which is 10.8 for y. Then 15 divided by .6 equals to 25
