2(2) + 3(3) =
4 + 9 = 13
I don't know what 90p means but basically, u have to multiply that by 3 and add it to our current total which is 13.
Then, u substract the total cost from the 20 and you should get the change.
Answer:
The solution set is (4, 3)
Step-by-step explanation:
To solve by substitution, start by solving the second equation for y.
2x - y = 5
-y = -2x + 5
y = 2x - 5
Now that we have this, put that expression in for y in the first equation and solve for x.
5x - 2(2x - 5) = 14
5x - 4x + 10 = 14
x + 10 = 14
x = 4
Now that we have the value of x, input it into either equation and solve for y.
2x - y = 5
2(4) - y = 5
8 - y = 5
-y = -3
y = 3
-5 + 4 = -1
start at -5 on ur number line....and since u r adding 4, move 4 spaces to the right and u should arrive at -1
In this question, we are required to find the total amount he paid to buy the shirt.
It is given that sales tax is 5.5 % over the amount paid.
The cost price of the shirt = $ 24.
The total amount will be = Cost price + 5.5 % of Cost price
Or
Total amount paid = $ 24 × 1.055 (i.e. 100 % + 5.5 %)
Total amount = $ 24 + (5.5 % × $ 24)
Total amount paid = $ 24 + $ 1.32 = $ 25.32
