Answer:
(a) The monthly budget for housing would range from $2,291.50-$2,749.80.
the good estimate would be $2,566.48.
(b) The monthly budget for housing would range from $1,250-$1,500.
the good estimate would be $1,400.
Step-by-step explanation:
Explanation with steps are in the following attachment
The first way is to cross multiply
4/5 = 28/x
4x = 5*28
4x = 140
4x/4 = 140/4
x = 35 which is the answer
=============================================
The second method is to note the denominators 4 and 28, and to ask yourself "what times 4 gets me 28?". The answer being 7, so 7*4 = 28. If you multiply top and bottom of the fraction 4/5 by 7, then you end up with 7*4 = 28 up top and 7*5 = 35 down below. This is another way of seeing how 4/5 = 28/35
Either way, the answer is x = 35
Answer:
Step-by-step explanation:
To find a linear model, you need to use the formula y = kx and solve that for k. k is the constant of variation, also known as the slope of a line. Hence, the word "linear".
If y = kx and y = 1010 and x = 5, then
1010 = 5k so
k = 202
The linear model, then, is
y = 202x
Obviously (D)
Because it increases $0.50 every morning.
