Lostsunrise [7]

Answer:

5 weeks

Step-by-step explanation:

We know that she works at a rate of $12 an hour, she also works 20 hours a week.

The total amount she makes per week is $240 (12 x 20). However, that is without deductions. We have to subtract $34 from the $240.

$240 - $34 = $206.

$206 is the amount she makes in a week and she wants to save $950. How many weeks does she have to save? Well, let's divide.

$950 / $206 = 4.6 weeks. However, if we have to round up to 5 weeks.

Jai Narayan sells two radio sets for 2288 each.

san4es73 [151]

Answer:

Step-by-step explanation:

S.P of each radio=$ 2288

Total S.P= $2\times 2288=$ $4576

Gain=10%

Lose=10%

C.P= $\frac{S.P\times 100}{100+gain(in\;percent)}$

C.P= $\frac{S.P\times 100}{100-loss(in\;percent)}$

By using the formula

C.P of one radio= $\frac{2288\times 100}{110}=$ $2080

C.P of another radio= $\frac{2288\times 100}{100-10}$ =$2542.2

Total C.P of two radios=2080+2542.2=$4622.2

Total C.P >Total S.P

Loss=S.P-C.P

Loss=4622.2-4576=$46.2

Loss%= $\frac{Loss}{C.P}\times 100$

Loss %= $\frac{46.2}{4622.2}\times 100=$ 1%

Hence, his loss 1%

Nick bought t candies and divided them equally between his y friends and me. Each of us got 7 candies.

inysia [295]

<h2>Hello!</h2><h2>Let me help you.</h2>

As I understand, you need to write an equation that relates $t \ and \ y$ . This problem will be solved using equations. The problem states:

<em>Nick bought t candies and divided them equally between his y friends and me. Each of us got 7 candies.</em>

<em />

From this statement, we know that:

t: Number of candies Nick bought.

y: Number of friends.

Since I am included in this problem, the number of people involved here can be expressed as:

$y+1$

Since each of us got 7 candies, then it is true that:

$\frac{t}{y+1}=7 \\ \\ t=7(y+1)$

<em>So t (number of candies) is a function of y(number of friends).</em>
