Answer:

Option (b) is correct.

Michelle buys 4 hot dogs and 2 hamburgers.

Step-by-step explanation:

Given : Michelle spent $32 on hot dogs and hamburgers. Hot dogs were $5 and hamburgers $6.if she bought a total of 6 items .

We have to find the number of each item she buys.

Let she buys x hotdogs and y hamburger

Given she buys 6 items

So, x + y = 6

and cost of one hot dog is $5

so , cost of x hot dog is 5x

also, cost of one hamburger is $6

so , cost of y hamburger is 6y

Given : she spent $32 on both

Thus, 5x + 6y = 32

Thus, The two equation becomes,

x + y = 6  ..(1)

and 5x + 6y = 32  ......(2)

Solving system using elimination method,

multiply equation (1) by 6 ,we get,

6x + 6y = 36 ....(3)

Now, subtract (2) from (3), we have ,

6x + 6y - (5x + 6y) = 36 - 32

Simplify, we have,

x = 4

Put x= 4 in (1), we have,

y = 6 - 4

y= 2

Thus, Michelle buys 4 hot dogs and 2 hamburgers.

The expression i/pt represents the rate of instrest being charged if a loan of p dollars for t years required i dollars in intre
zysi [14]

Answer:

7.3%

Step-by-step explanation:

Given:

<em>Formula for Rate of interest </em>R:

R=\dfrac{i}{Pt}

Where i is the rate of interest.

P dollars is the loan and

t years is the time for which interest is to be paid

P =\$690\\t=3\ years\\i=\$151.11

To find:

R=?

Solution:

Putting the given values in the formula:

R=\dfrac{151.11}{690 \times 3}\\\Rightarrow R=\dfrac{151.11}{2070}\\\Rightarrow R=0.073

Multiply the above value with 100 to find the percentage.

i.e.

R=0.073\times 100 = \bold{7.3\%}

Therefore, the answer is <em>7.3%</em>

x in (-oo:+oo)

(x/4)/3 = 6 // - 6

(x/4)/3-6 = 0

1/12*x-6 = 0 // + 6

1/12*x = 6 // : 1/12

x = 6/1/12
