Answer:

Final answer:

To simplify the given expression, solve the innermost parentheses first, followed by simplifying the expression within the brackets, and finally performing addition. The simplified expression is 56.

Explanation:

To simplify the given expression, we need to follow the order of operations (PEMDAS/BODMAS). In the given expression, we start by solving the innermost parentheses first:
9(1+3) = 9(4) = 36.
Then, we simplify the expression inside the brackets:
[60 - 36] = 24.
Finally, we substitute the value of the simplified expression back into the original expression:
-6 + {14 + 2 × 24} = -6 + {14 + 48}.

Further simplification within the brackets:
-6 + {62}.
And finally, performing the addition:
-6 + 62 = 56.

Therefore, the simplified expression is 56.

The prices of RacerZ and the Swiftee bicycles are $142 and $154.78.

What is multiplication?

In Maths, the basic explanation of multiplication is adding a number, with respect to another number, repeatedly.

Given that, The Speed monster's price is $64.80. The RacerZ is $20 less than 2.5 times the price of the Speed monster. The Swiftee is 1.09 times the price of the RacerZ.

According to question,

Price of RacerZ = 2.5*64.80-20 = $142

Price of Swiftee = 142*1.09 = $154.78

Hence, The prices of RacerZ and the Swiftee bicycles are $142 and $154.78.
