Answer:
19(200+4d)+25(50+5d)
Step-by-step explanation:
To represent this as an expression, we could multiply the amount of each booth by their own equations and expenses. The expression for a food booth is 200+4d, since they charge 200 at the start and add 4 dollars for every day.
The expression for the game booth is 50+5d, since they charge 50 initially and charge 5 for every day.
Now we can just multiply the expressions by their amount and add them together.
19(200+4d)+25(50+5d)
There's your expression!
Hope this helps :D
Answer: (a,b)= (7.13 ,-8.27)
Step-by-step explanation:
From the data, we have
A-B+3C=0
where, A= (-8.6, 18.0)
B= (12.8, -6.8)
and let C= (a, b)
So, putting values
(-8.6, 18.0) - (12.8, -6.8) + 3(a,b)=0
3(a,b) + (-21.4, 24.8) = 0
3(a,b)= (21.4, -24.8)
(a,b)= (7.13 ,-8.27)
