Porter is visiting India and would like to purchase some local spices. He finds some spices that cost 401.39 rupees. If the curr

Murljashka [212]

The cost of spices in US dollars is $5.45

The cost of spices in Indian rupees = 401.39 rupees

The exchange rate is

1 dollar:73.6500 rupees

So we have to exchange the Indian rupees to the US dollars

The cost of spices in Indian rupees = 401.39 rupees

The cost of spices in US dollars = The cost of spices in Indian rupees / 73.6500

Substitute the values in the equation and fins the cost of spices in US dollars

The cost of spices in US dollars = 401.39 / 73.6500

Divide the numbers

= $5.45

Hence, the cost of spices in US dollars is $5.45

mote1985 [20]

She would make 3.00 dollars

50(10) - 20(10) = (10)(50 - 20)

500 - 200 = (10 * 30)

300 = 300

(10)(50 - 20) = 30(10)

(10 * 30) = 300

300 = 300

35% of the students at charles drew middle school are 6th graders if there are 84 sixth graders what is the total number of stud

Juliette [100K]

Answer: The total number of student in the school = 240.

Step-by-step explanation:

Let x be the total number of students in the school.

Given: 35% of the students at Charles drew middle school are 6th graders.

i.e. Number of sixth graders = 35% of x = 0.35x [35% = 0.35]

Since there are 84 sixth graders in the school,

So $0.35x=84$

Divide both sides by 0.35, we get

$x=\dfrac{84}{0.35}=\dfrac{84\times100}{35}=240$

Hence, the total number of student in the school = 240.
