This isn't enough information to answer the question. We need to know if he mowed the same lawn 5 times, 5 different lawns, and so on.
If he mowed one lawn 5 times, that would be $150 but if he mowed lawns for different people then the answer is None of the choices are correct because you can eliminate the first two choices for being too low for any possible scenario.
Answer:
7x+1
Step-by-step explanation:
When you look at the expression(3x+2+4x-1), you will notice that some have variables while some are just regular numbers.
First, focus on the variables. 3x and +4x. In the expression, you will have to add it so 3x+4x will be 7x. Now, keep 7x on the side and switch to the numbers.
Next, focus on the numbers. 2 and -1. All you have to do is combine them which will be 2-1 which also equals 1.
Finally, return 7x with 1 which will be 7x+1. The reason you add a + sign instead of a - sign is because you got positive 1, not negative 1.
Your answer is 7x+1.
The unknown scale factor above is calculated by dividing the true value of the length of the banner by the length in the photograph. If we take the first dimension that is 8 inches only in photograph but 12 feet in the banner.
scale factor = (12 ft)(12 inches/ 1 ft) ÷ 8 inches
scale factor = 18
Therefore, the scale factor is 18:1. The answer to this item is letter D.
