The correct answer is 34.4
Answer:
Price is $1088 (agrees with answer B)
Step-by-step explanation:
Notice that the linear equation that represents this relationship can be estimated via finding the slope and y-intercept using a couple of the given points on the plane (for example (5, 140), and (10, 200), which results in;
Price = 12 x + 80
where "x" is the number of computers shipped.
Then, to ship 84 computers, we have the following price:
Price = 12 (84) + 80 = 1088
Then the price is $1088.
Answer:
gas = $0.23, electricity = $0.10
Step-by-step explanation:
-2(1+5a)=-6(a+3)
Expand the brackets:
-2-10a=-6a-18
Add 10a to each side:
-2=4a-18
Add 18 to each side:
16=4a
Divide each side by 4:
4=a
Hope this helps :)
