8x+15=7
In the statement the phrase the sum of can tell you that it is going to be an addition problem. So 8x ( eight times a number) would be added to the 15, 8x+15. Since its an addition problem the part where it says ' ... is seven', you know that it will all equal 7. So the answer would be 8x+15=7.
The number 1.04 represents the rate at which the house appreciates, or increases in its price annually.
As according to the values of an exponential equation, which is represented by this: y=ab^x, the a value represents the original price, the b value represents the rate of growth/decay (if growth, you add 1 to the rate, if decay, you subtract the rate from 1), and x represents the amount of times it decays or grows.
As according to the function <span> f(x) = 242,000(1.04)^x, 242,000 is the original price and 1.04 is the rate of growth since 1 has been added to the the 4% annual growth.</span>

Since the frozen dinner at the grocery store was bumped up by 40%, the new price would have been $3.08
Now, a customer wants to buy 4 frozen dinners, so multiply the price of one frozen dinner by 4.
$3.08 x 4 = $12.32
There is a 9% sales tax put up for the grocery store. You will want to multiply 9% (or .09) times the price of the 4 frozen dinners.
$12.32 x .09 ~ $1.11
Add the sales tax price to the price of the four frozen dinners.
$12.32 + $1.11 = $13.43
$13.43 will be the amount the customer will pay.
