Answer:
D. 11
Step-by-step explanation:
T = total savings
w = number of weeks
Paige:
T = 350 + 25w
Cindy:
T = 190 + 40w
In how many weeks will Cindy have more money in her savings than Paige
Equate the total savings of both of them
350 + 25w = 190 + 40w
Collect like terms
350 - 190 = 40w - 25w
160 = 15w
w = 160/15
w = 10.67
Approximately,
In 11 weeks, will Cindy have more money in her savings than Paige
Check:
Paige:
T = 350 + 25w
= 350 + 25(11)
= 350 + 275
= 625
Cindy:
T = 190 + 40w
= 190 + 40(11)
= 190 + 440
= 630

Answer:
B. He added 3.5 and 5 when he should have multiplied them.
Step-by-step explanation:
Let's observe Joe's steps:
- V = lwh
- 204 = 3.5 * (5) * l
Here, * means to multiply, so we're supposed to multiply 3.5 to 5, which would give you the answer 17.5. Unfortunately, look what Joe got: he obtained the value of 8.5, and if we observe, 3.5 + 5 = 8.5.
That's how we know that Joe added instead of multiplied, as he should have done. Thus, the answer is B.

A. We are given that each person weighs 150 lb, each gear
per person weighs 10 lb, and a total of 200 pounds of gear for the boat itself.
Since each person only carries one gear, therefore total
weight per person in 160 lb (weight of person + weight of gear).
So let us say that x is the number of persons, the
inequality equation is:
160 x + 200 ≤ 1200
B. There are three groups that wish to rent the boat.
> Solve the inequality equation when x = 4
160 (4) + 200 ≤ 1200
840 ≤ 1200 (TRUE)
> Solve the inequality equation when x = 5
160 (5) + 200 ≤ 1200
1000 ≤ 1200 (TRUE)
> Solve the inequality equation when x = 8
160 (8) + 200 ≤ 1200
1480 ≤ 1200 (FALSE)
So only the 4 people group and 5 people group can safely
run the boat.
C. Find the maximum number of people that may safely use
the boat, solve for x:
160 x + 200 ≤ 1200
160 x ≤ 1000
x ≤ 6.25
Therefore the maximum number of people that can safely
use the boat is 6 people.
