The number of weeks it will take both Sam and Marshall to have the same amount of savings in their accounts is 48 weeks
Given:
<em>Amount with Sam </em>= $2,500
<em>Additional savings each week</em> = $40
<em>Amount with Marshal</em> = $7,300
<em>Amount spent each week</em> = $60
let
x = <em>number of weeks</em>
<em>Sam equation:</em>
2500 + 40x
<em>Marshall's equation:</em>
7300 - 60x
Equate both
2500 + 40x = 7300 - 60x
<em>collect like terms</em>
2500 - 7300 = - 60x - 40x
-4800 = -100x
divide both sides by - 100
x = -4800 / -100
x = 48 weeks
Therefore, the number of weeks it will take both Sam and Marshall to have the same amount of savings in their accounts is 48 weeks

Answer:
After 40 weeks
Step-by-step explanation:
To get the answer to this question, we need to first know the difference in the amount of money deposited by the 2 individuals and in this case it us $400 since one deposited $500 and the other $100
The next thing to do is to divide the difference in amount(400) by the amount contributed by each person per week.
Catherine deposits $20 per week
400/20 = 20
Lance deposits $10 per week
400/10 = 40
The LCM between 40 and 20 is 40 weeks.
Therefore, both individuals need to deposit money for 40 weeks for both of their savings to be the same.
If Catherine deposits $20 for 40 weeks,she will have 40 × 20 = $800 + $100(initial deposit that she made) = $900
Lance deposits $10 for for 40 weeks and he will have 40 × 10 = $400 + $500(initial deposit made by him)= $900
Answer:
<em>180</em>
Step-by-step explanation:
You need to find 3/8 of 480.
To find a fraction of a number, multiply the fraction by the number.
3/8 of 480 =
= 3/8 * 480
= 3/8 *480/1
= (3 * 480)/(8 * 1)
= 1440/8
= 180
Answer:
1/2
Step-by-step explanation:
x∧(3/2) = 64 = 8²
(3/2)Log₈ x = 2 Log₈ 8
Log₈ x = 4/3
x = 8∧(4/3)
Therefore
4* x∧(-3/4) = 4* 8∧(-1) = 4/8 = 1/2 = 0.5
Answer: 25% off
Step-by-step explanation:
1= 0.25 + 0.75
25% is off is the equivalency of multiplying the value of the original cost with 0.75.
20*0.75=15
