-5 ( -2 add 7 to both sides
-6 ( -3 divide both sides by -3
7) - 4 subtract 7 from both sides
-1 ) -8 multiply both sides by -2
The new price for the jelly cake is $75 as the store increases its purchase price.
A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100.
The proportion therefore refers to a component per hundred. Per 100 is what the word percent means. The letter "%" stands for it.
Initial price of jelly cake is = $25.
Increase in price of jelly cake is = 200%.
Hence, increase in price of jelly cake is = $25 × 20%
= $25 × (200/100)
= $25 × 2
= $50.
Hence, the new price for the jelly cake is = initial price + increase in price
= $25 + $50
= $75.
Therefore, the new price for the jelly cake is $75.

Answer:pythagoream theorem applies to right angle triangle.
Formula
C^2= a^2 + b^ 2
Where a&b are the two sides of the triangle so we need to find side c.
C^2 = 35.42^2+ 21.64^2
C^2 = 1254.57 + 468.29
C^2 = 1722.86
C = square root of 1722.86
C= 41.51m
Area of triangle
A = ab/2
A = 35.42 x 21.64/2
A = 383.24.
