She can buy 3 tubes be cause 8.50 time 2 is less then 20$ but 8.50 times three is more than 20$ its 25.5
X + 6.38 = 15.75<span> would be the answer
x=9.37
for the first option, you are not adding 15.75 and x together.
for the second option, it is correct, because in the problem, it is giving the operation, 15.75-6.38=x. when you turn it do inverse operation, you get </span><span>x + 6.38 = 15.75.
for the third option, it doesn't make sense and it's not doing what the problem is asking for.
for the fourth option, you are not multiplying. you are subtracting </span>15.75 by<span> 6.38 to get x.</span>

Step-by-step explanation:
Answer:%80 or 0.8
Step-by-step explanation:
Total = 7.50
Part of 7.50 is 6
The percentage of 6 in 7.50 is 6*100/7.50
0.8* 100
80%
Or you could do it this way:
6/7.5
x10 on both
60/75
by 5 times
12/15
4/5
=0.8
solve for "x" to see how many minutes,
if you get a decimal amount, like 2.17, multiply the .17 times 60
to get the seconds
or do it in seconds
