Answer:
(0,2)(1,-4)((-1,8)
Step-by-step explanation:
Let x represent the # of people in sid’s group: 200 - (16.25x + 6.50x) = 18.25
200 - 22.75x = 18.25
-22.75x = -181.75
x = about 8
if Sid is not included in the group, i think the answer is D. 7, but im not sure
You need one equation for the physical nickels and dimes, which total to 21:
n+d=21
Secondly, you need one equation for the numerical value of those nickels and dimes. We know nickels are worth $0.05 and dime are worth $0.10:
.05n+.1d=1.70
