Final answer:
Jesse should multiply the total cost of Band Camp by 60/100 to find out how much money he needs to save; in this case, it's $300.
Step-by-step explanation:
To determine how much money Jesse would need to save to go to Band Camp, which costs $500 and requires saving 60% of the total cost, Jesse should use the method of multiplying the total cost by the percentage that needs to be saved, expressed as a fraction. This can be done by using option (d), which is: multiply 500 by 60/100. To perform the calculation, Jesse would take the total cost of $500 and multiply it by 0.60 (which is 60% written as a decimal). This will give the amount needed to save:
Amount to Save = $500 × 0.60 = $300
Therefore, Jesse needs to save $300 to go to Band Camp.
