Answer:
1. x + y = 25
2. x - y = 7
3. x = 16, y = 9
Step-by-step explanation:
(x + y = 25) + (x - y = 7)
2x (the y cancels) = 32
32/2 = 16, x = 16
substitute x in either equation
16 + y = 25
y = 9
You would distribute multiply every thing inside the parenthesis by the number on the out side of it on the the left the go to the other side of the addition sign and do the same then combine like terms

Answer:
<h2>$42</h2>
Step-by-step explanation:
By definition, Markup is the difference between a product's selling price and cost as a percentage of the cost.
For example, if a product sells for $125 and costs $100, the additional price increase is ($125 – $100) / $100) x 100 = 25%.
Given data
firstly let us solve for 40% of $30
=40/100*30
=0.4*30
=$12
therefore the sale price will be the markup rate plus the initial price
<em>Hence the you will have to pay 12+30=$42</em>
14 3/8 pounds because 5 3/4 * 2 1/2 = 14 3/8
