Answer:
-7 times 6 equals -42
Step-by-step explanation:
<span>We simplify the equation to the form, which is simple to understand
<span>q+2/5=2q-11/7
Simplifying:
<span>q + 0.4=2q-11/7
Simplifying:
<span>q + 0.4=2q-1.57142857143
We move all terms containing q to the left and all other terms to the right.
<span>+1q-2q=-1.57142857143-0.4
We simplify left and right side of the equation.
<span>-1q=-1.97142857143
We divide both sides of the equation by -1 to get q.
<span>q=1.97142857143</span></span></span></span></span></span></span>
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.
