Answer: He made $90 last week.
Assumption :
Let, Luis made $X last week.
He made $72 this week which is 80% of $X that he made last week
⇒ X * 80% = 72
⇒ X * 80/100 = 72
⇒ X = (72 * 100)/80
⇒ X = 90
Therefore, he made $90 last week.
To remember :
While solving this type of problems, be careful to understand which one of last time and current time is not given; just assume that one and input other conditions, the problem will be solved.
You would use PEMDAS
But since any number divided by 1 is the number by which it is divided by then you can eliminate that. Now your problem looks like this:
8✖️4➕9✖️56➕57
Since there are no parentheses or exponents then you would multiply.
8✖️4= 32
32➕9✖️56➕57
Then multiply the other multiplication problem.
9✖️56= 504
32➕504➕57
Now you can add all of the numbers together
32➕504=536
536➕57=593
Your answer is 593
Hope this helps! :3
Answer: has no equal sign
Answer:11/14
Step-by-step explanation:
Let's multiply the numerators first. 22 x 1 is 22, so your numerator is 22.
The denominator: 7 x 4= 28, your denominator is 28.
Your answer <u><em>would</em></u> be 22/28.
However, we can simplify this.
22 and 28 are both divisible by 2.
22/2=11
28/2=14
Your final answer is <u><em>11/14</em></u>
