Dan earns £9.30 per hour. How much will he earn for 9 hours work?

Dimas [21]

Answer: £83.70

We can set up a ratio.

Let x be the amount he earns for 9 hours of work.

$\frac{9.30 pounds}{1 hour} = \frac{x pounds}{9 hours}$

We can cross multiply:

x = £83.70

Step-by-step explanation:

If first odd number is x

THen next consecutive odd number is x + 2

Next one is x + 4

Now, we can write the word problem as:

$x+x+2+x+4 \leq 33$

Now we solve:

$x+x+2+x+4 \leq 33\\3x+6 \leq 33\\3x \leq 27\\x \leq 9$

So, x is less than or equal to 9, so it can be

9, 7, 5 .....

What is the maximum value of the lowest number (x)?? It is 9
