Answer:
350 he wants 100 so if he withdraws 15 a week for chickfala he would maybe need to get chickfala every 2 weeks?
Step-by-step explanation:
The system of linear equations can be used to find the number of nickels, n, and the number of quarters, q, yolanda used is n + q = 28
n + q = 280.05n + 0.25q = 4
<h3>Simultaneous equation</h3>
n + q = 28
0.05n + 0.25q = 4
n = 28 - q
0.05n + 0.25q = 4
0.05(28 - q) + 0.25q = 4
1.4 - 0.05q + 0.25q = 4
- 0.05q + 0.25q = 4 - 1.4
0.20q = 2.6
q = 2.6 / 0.20
q = 13
Substitute into
n + q = 28
n + 13 = 28
n = 28 - 13
n = 15
