Digiron [165]

Answer:

94 boxes of samoas

131 boxes of thin mints

Step-by-step explanation:

m=mints

s=samoas

s+m=225 m=225-s

s(2.5)+m(3)=628

2.5s+3m=628

substitute for m

2.5s+3(225-s)=628

2.5s+675-3s=628

reduce

-0.5s=-47

s=94

<h3>What is Percentage?</h3>

A percentage is a way to describe a part of a whole. such as the fraction 1/4 can be described as 0.25 which is equal to 25%.

To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.

It is given that the production of footwear in 2006 was 1.8 billion which will be reduced by 8.4%, therefore, the number of footwear that will be produced in 2016 is 91.6%(100%-8.4%) of the production in 2006. Therefore, the production of footwear in 2016 will be

$91.6\%\ of\ 2006\\\\= 0.916 \times 1.8\ billion \\\\= 1.6488\approx 1.65\ billion$

Hence, the production of the footwear that will be in 2016 will be 1.65 billion.

the table above represents the relationship between the independent variable x and the dependant variable y. identify the domain

olga2289 [7]

Answer:

Domain can be found in the x axis, while range is found in the y axis. You didn't list the chart, however whatever numbers are listed for x, would be considered the domain.

Example:

x - 1,2,3,4,5

y - 1,1,2,3,4,

domain: 1,2,3,4,5 - range: 1,2,3,4

If there are repeating numbers in any of the axises, only list them once.
