Answer:
That is to say that at 3 months, the values of the club are equal.
Club A = 268 dollars in total
Club B = 295 dollars in total
Step-by-step explanation:
The first thing is to propose an equation for each club. Let m be the number of months.
Club A = 28 + 20 * m
Club B = 19 + 23 * m
Now, to know when it is the same, we must equal the value of Club A with Club B, it would look like this
28 + 20 * m = 19 + 23 * m
By rearranging the equation we have:
23 * m - 20 * m = 28-19
3 * m = 9
m = 3
That is to say that at 3 months, the values of the club are equal.
Now to know the total value, we will do it with an annual membership, which would be a total of 12 months, therefore it is to replace in the equation of each one:
Club A = 28 + 20 * 12 = 268 dollars in total
Club B = 19 + 23 * 12 = 295 dollars in total
Answer:
t = -5
Step-by-step explanation:
Solve for t:
5 (t - 3) - 2 t = -30
Hint: | Distribute 5 over t - 3.
5 (t - 3) = 5 t - 15:
5 t - 15 - 2 t = -30
Hint: | Group like terms in 5 t - 2 t - 15.
Grouping like terms, 5 t - 2 t - 15 = (5 t - 2 t) - 15:
(5 t - 2 t) - 15 = -30
Hint: | Combine like terms in 5 t - 2 t.
5 t - 2 t = 3 t:
3 t - 15 = -30
Hint: | Isolate terms with t to the left hand side.
Add 15 to both sides:
3 t + (15 - 15) = 15 - 30
Hint: | Look for the difference of two identical terms.
15 - 15 = 0:
3 t = 15 - 30
Hint: | Evaluate 15 - 30.
15 - 30 = -15:
3 t = -15
Hint: | Divide both sides by a constant to simplify the equation.
Divide both sides of 3 t = -15 by 3:
(3 t)/3 = (-15)/3
Hint: | Any nonzero number divided by itself is one.
3/3 = 1:
t = (-15)/3
Hint: | Reduce (-15)/3 to lowest terms. Start by finding the GCD of -15 and 3.
The gcd of -15 and 3 is 3, so (-15)/3 = (3 (-5))/(3×1) = 3/3×-5 = -5:
Answer: t = -5
