Final answer:
Leo has 74.3% of the total cost of the skiing lessons.
Step-by-step explanation:
Leo wants to buy 35 skiing lessons that cost $50 each. He only has $1300. To find the percentage of the total cost of the lessons Leo has, we need to divide the amount he has by the total cost of the lessons and then multiply by 100.
Total cost of the lessons = $50 x 35
= $1750
Percentage of the total cost Leo has = (1300 / 1750) x 100
= 74.3%
