The total budget allocation for Residential infrastructure is $1,500,000. Based on the surveyor estimate, total cost for the houses built in medium sized blocks is doubled the total cost for the small sized blocks. Total cost for the houses built in large sized blocks is $250,000 more than the total cost for the houses built in medium sized blocks. 2) Declare a suitable variable and write an equation and solve it to find the budget allocation for each area. a. What is the ratio of estimated total costs for houses of small sized blocks, medium sized blocks, and large sized blocks? b. Develop three linear equations to represent the relationship between the budget (y) and the number of houses (x) of each block sizes. c. Assume that you created three separate linear graphs based on the equations developed in (b). Find gradients of each of them and explain its significance in terms of budget distribution.

Write an equation relating the variables in each of the following situations. a. The pay P for t hours at $17 an hour. b. The total pay P for a day of t working hours on which you charge a base rate of $26 and $19 for each hour worked. c. The total pay P for t hours at $20 for the first hour and $14 for each additional hour.

Hello, I want to know what the remaining debt will be after 10, 15, and 25 years for each plan. If you want more details it is in the second image. Thanks!

when comparing equations 3 and 4. how was it determined that b = 1 and c = 1?
