Question 237222: your company produces two models of bikes Model A and Model B Model A takes 2 hours to assemble and Model B takes 3 hours to assemble. Model A cost $25 to make each bike where Model B costs $30 to make per bike. If your company has 34 hours and $350 per day for these two bikes, how many of each can be made in a day? Solve equation using substitution or elimination. Explain how to check your solution for both equations.
You can put this solution on YOUR website! your company produces two models of bikes Model A and Model B Model A takes 2 hours to assemble and Model B takes 3 hours to assemble. Model A cost $25 to make each bike where Model B costs $30 to make per bike. If your company has 34 hours and $350 per day for these two bikes, how many of each can be made in a day? Solve equation using substitution or elimination. Explain how to check your solution for both equations.
:
Let a = no. of Model A bikes
Let b = no. of B Model
:
The hrs constraint
2a + 3b = 34
:
the cost constraint
25a + 30b = 350
:
Multiply the 1st equation by 10, subtract from the above equation
25a + 30b = 350
20a + 30b = 340
------------------subtraction eliminates b, find a
5a = 10
a = 2 Model A bikes
then using the 1st equation
2(2) + 3b = 34
4 + 3b = 34
3b = 34 - 4
3b = 30
b = 10 model B bikes
;
:
Check in the cost equation
25(2) + 30(10) = 350
