Adam's dad paid £52.20.
This is considered three "parts" of the total cost.
Let's divide by 3 to find the size of one part.
£52.20 ÷ 3 = £17.40
Now, multiply by 5 (Adam's parts + his dad's) to get the total cost.
Answer:
32
Step-by-step explanation:
We are given the expression:

and asked to evaluate the expression.
Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction.
Solve inside the parentheses first. Subtract 37 from 13.
⇒ 13-37= -24

Next, multiply -8 and -24.
⇒ -8*-24= 192

Finally. divide 192 by 6.
⇒ 192/6 = 32

When evaluated, the expression -8(13-37)/6 is equal to 32.
