The baker:
On Monday. The baker baked 36 blueberry muffins and this is 40% of the total she makes. Assuming the total is x, the expression would be:
36 = x × 40%
36 = 0.4x
x = 36 / 0.4
= 90 muffins in total
On Tuesday, she makes 60 muffins of which blueberry muffins are 40%:
= 60 × 40%
= 24 blueberry muffins
In conclusion, the Baker baked 90 muffins in total on Monday and 24 blueberry muffins on Tuesday.

Answer:
Part A: 90; Part B: 24.
Step-by-step explanation:
The number of blueberry muffins is 40% of the total number of muffins.
Part A: There are 36 blueberry muffins. This is 40% of the unknown number of muffins, x; this gives us
36 = 0.4x
Divide both sides by 0.4:
36/0.4 = 0.4x/0.4
90 = x
There were 90 total muffins.
Part B: 40% of the total number of muffins, 60, gives us the unknown number of blueberry muffins:
0.4(60) = x
24 = x
There were 24 blueberry muffins.
Answer:
Step-by-step explanation:
Given equation,
For getting the equation for x,
We need to isolate x in the left side,
Subtract c on both sides of equation (1),
Divide both sides by A,
Which is the required equation.
A.
t < –18.5 and t may be a negative number.
B.
t < –18.5 and t must be a positive number.
C.
t > –18.5 and t may be a negative number.
D.
t > –18.5 and t must be a positive number.
please help Ive got 4 more questions
Answer:
1. Find the value of the discount amount, and subtract from the original.
2. Find the value of the item after discount by using 100%-30%.
I prefer the second, as it is faster.
Step-by-step explanation:
1. Find the value of the discount amount, and subtract from the original.
Say y is the amount you pay after the discount, and x is the original price, the calculation will look like this:
The value of the discount is 30% of x, which is equal to 0.3x.
subtract that from the original value to find y:
y = x - 0.3x
2. Find the value of the item after discount by using 100%-30%.
The amount left over after subtraction thirty % is 70%
Thus,
y = 0.7 x
