Answer:
140 coins
Step-by-step explanation:
To calculate the total number of coins Kate have in her collection, we can use the rule of three:
The problem says that 7 of her coins are equivalent of 5% of her entire collection, and we want to know the total number of coins (100%) of her collection. So, if 7 coins are 5%, how much coins are 100%:
7 -> 5%
X -> 100%
7/X = 5/100
X = 100*7/5 = 140 coins
Answer:
Step-by-step explanation:
um
37.5 = initial rate
44.9 = slope/rate
In problems like these, just use y = initial rate + rate(variable)
In this case, the answer would be y = 37.5 + 44.9h
0.7 / 100 = 0.007 or 0.007 x 100 = 0.7 hope this helps
