10 + 12 + 23 ÷ 3 = 15
22 + 23 ÷ 3 =15
45 ÷ 3 = 15
The missing number would be 23 since 22 + 23 is 45 and 45 divided by 3 is 15.
Hope this helped :)
Answer:
28.44$
Step-by-step explanation:
The original price of a shirt is A.
This shirt is on sale for 25% => the price of that shirt after being sale:
P1 = A - A x 25% = A - A x (25/100) = A - A x (1/4) = A x (3/4)
This shirt is discounted one more time for 25% => the price of that shirt after being discounted second time.
P2 = P1 - P1 x 25% = P1 - P1 x (25/100) = P1 - P1 x (1/4) = P1 x (3/4) = A x (3/4)^2
P2 is given to be equal to 16$, then there is an expression:
P2 = 16
or
A x (3/4)^2 = 16
=> A x (9/16) = 16
=> A = 16 x (16/9) = 28.44$
