Answer:
$3 from his pockets
Step-by-step explanation:
Great question, it is always good to ask away and get rid of any doubts that you may be having.
To begin solving this problem we need to first calculate how much money all the supplies will cost. We do this buy adding up the prices of each individual supply. Like so,
Now we can see that the total amount of the supplies is $13. Since his mom loaned him $10 we can subtract that from the total cost.
Finally, we can see that Juan would need to pay a total of $3 from his pockets to be able to buy all the ingredients.
A=xy
If there is 10% increase in x then,
New value of x = x + 10%of x =1.1x
similarly for y
New value of y after increase= 1.1 y
New value of A after increase in x and y = 1 .1x × 1.1 y= 1.21xy
now
increase amount in A= New value of A - old value of A
=1.21xy - xy= 0.21xy
percentage increase in A= (0.21xy÷xy )× 100= 21%
