The number is 125 and the equation is 0.8x = 100
Step-by-step explanation:
80% of x is equal to 100.
Write an equation that shows the relationship of 80%, x, and 100
80% = 0.8
0.8x = 100
x = 100/0.8
x = 125
The number is 125 and the equation is 0.8x = 100
The number of blueberries sold is 30 and the number of strawberries sold is 60.
<h3>How to form an equation?</h3>
Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.
In other words, an equation is a set of variables that are constrained through a situation or case.
Let's say Dalvin sold S pounds of strawberries and b pounds of blueberries.
Given that,
Cost of each pound of strawberries = $2
The cost of s pound of strawberries will be 2s.
Cost of each pound of blueberries= $3.50
The cost of b pound of blueberries will be 3.5b
Total cost 2s + 3.5b = 225(given)
And,
s = 2b (given)
Now,
By substitution
4b + 3.5b = 225 ⇒ b = 30
And again substitution
s = 2(30) = 60
Hence "The number of blueberries sold is 30 and the number of strawberries sold is 60".
