Final answer:
To find the total cost, calculate 5/6 of the blue swimsuit's cost, which is $35 for the red swimsuit, and add it to the blue swimsuit's cost of $42, resulting in a total of $77.
Step-by-step explanation:
The question asks us to calculate the total cost of two items that are priced differently. We know that the blue swimsuit costs $42 and that the red swimsuit costs 5/6 as much as the blue one. First, to find the cost of the red swimsuit, we calculate 5/6 of $42.
Cost of the red swimsuit = 5/6 * $42 = $35.
Next, we add the cost of the blue swimsuit to the cost of the red swimsuit to find the total cost:
Total cost = Cost of blue swimsuit + Cost of red swimsuit = $42 + $35 = $77.
Therefore, the total cost of both swimsuits together is $77.
A calculation is a deliberate mathematical process that transforms one or more inputs into one or more outputs or results. The term is used in a variety of senses, from the very definite arithmetical calculation of using an algorithm, to the vague heuristics of calculating a strategy in a competition, or calculating the chance of a successful relationship between two people.
