A girl scout troop sold cookies. If the girls sold 5 more boxes the second week than they did the first, and if they doubled the

mihalych1998 [28]

We can let x be the number of boxes sold for the first week. We can as well express the number of boxes for the second and third week through x using the statements provided.

Since the girl scout sold 5 more boxes on the second week, we have (x + 5) number of boxes sold for the second week. Now, for the third week, since it's double that of the second week, we have 2(x + 5). Thus, we have the following:

first week: x
second week: x + 5
third week: 2(x + 5)

Given that the total number of boxes sold for the three weeks is 431. We have

x + (x + 5) + 2(x + 5) = 431
x + x + 5 + 2x + 10 = 431
4x + 15 = 431
4x = 431 - 15
4x = 416
x = 104

We have now the value of x. Using this, we can find the values for the second and third week.
x + 5 = `104 + 5 = 109
2(x + 5) = 2(109) = 218

Answer:
first week: 104
second week: 109
third week: 218

Can someone help me and explain it

g100num [7]

The answer is D. y=500+0.25x
let's say y represents his total payment each week and x represents his total sales
x=$500
since he always gets 25% bonus of his total sales,
25%.500=0.25x
so, his total payment equals to
y = 500+0.25x

Trey, Marco and Tina won a cash prize at a talent show. They decided to share the money evenly between them. When trey got home

cupoosta [38]

Answer:

$\frac{1}{6}$ fraction of the total money.

Step-by-step explanation:

Trey, Marco, and Tina won a cash prize at a talent show.

They decided to share the money evenly between them.

So, if the prize money is $x, then each of them gets $\frac{x}{3}$ amounts of money.

Now, Trey gives half of his money to his little sister.

So, his sister gets $\frac{x}{3} \times \frac{1}{2} = \frac{x}{6}$ amounts of money.

Therefore, Trey keeps for himself $\frac{x}{3} - \frac{x}{6} = \frac{x}{6}$ amounts of money.

So, it is $\frac{1}{6}$ fraction of the total money. (Answer)
