45 + 4 makes 49 if that counts
Using a system of equations, it is found that there are 5 dimes and 9 quarters in his pocket.
<h3>What is a system of equations?</h3>
A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, the variables are given as follows:
- Variable x: number of dimes in his pocket.
- Variable y: number of quarters in his pocket.
He has a total of 14 coins, hence:
x + y = 14 -> y = 14 - x.
They are worth $2.75, hence, considering the value of each coin(dimes $0.1 and quarters $0.25), we have that:
0.1x + 0.25y = 2.75
Since y = 14 - x:
0.1x + 0.25(14 - x) = 2.75
x = (0.25*14 - 2.75)/0.15.
x = 5.
y = 14 - x = 14 - 5 = 9.
There are 5 dimes and 9 quarters in his pocket.

Answer:
A) 250 / 8 = 31.25
31.25 x 8 = 250 Know you know that one pancake requires 31.25ml of Milk
31.25 x 4 = 125
So 4 pancakes requires 125ml of Milk
B) 5 / 8 = 0.625
0.625 x 8 = 5 So just like last time, you know that 0.625g of butter is required to make 8 pancakes
0.625 x 12 = 7.5g of Butter
So 12 pancakes requires 7.5g of butter.
Hope this makes sense !
