2x+4y+0.50z=36 represents the situation.
Step-by-step explanation:
Let,
Drinks = x
Sandwich = y
And,
Chips = z
Total amount on these items = $36
According to the statement;
![x(cost\ of\ one\ drink)+y(cost\ of\ one\ sandwich)+z(cost\ of\ one\ chips)=\ Total\ amount\ spent\\2x+4y+0.50z=36](https://tex.z-dn.net/?f=x%28cost%5C%20of%5C%20one%5C%20drink%29%2By%28cost%5C%20of%5C%20one%5C%20sandwich%29%2Bz%28cost%5C%20of%5C%20one%5C%20chips%29%3D%5C%20Total%5C%20amount%5C%20spent%5C%5C2x%2B4y%2B0.50z%3D36)
2x+4y+0.50z=36 represents the situation.

Answer:
3.1567 * 10^-4 miles
Step-by-step explanation:
1 ft = 1.894 * 10^-4 miles , so
1 inch = 1.894 * 10^-4 / 12 miles
= 0.15783 * 10^-4
= 1.5783* 10^-5 miles ( in scientific form).
Multiplying this by 20 we get
31.567 * 10^-5
= 3.1567 * 10^-4 miles.
