. MODELING REAL LIFE You save $20 each week to

buy a smart watch that costs $229.95.
a. Describe the numbers of months you need to
save to buy the smart watch.
b. Your parents give you $50 to help you buy
the smart watch. How does this affect your
answer in part (a)? Use an inequality to justify
your answer.

Answer 1

After doing mathematical operations, we can conclude that it would take is 12 months to buy the smart-watch for $229.95 if we save $20 per month.

What are mathematical operations?

• An operation is a function in mathematics that transforms zero or more input values into a clearly defined output value.
• The operation's arity is determined by the number of operands.
• The rules that specify the order in which we should solve an expression involving multiple operations are known as the order of operations.
• PEMDAS stands for Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction (from left to right).
