Cuz every 100cents is one dollar
Mrs. Richmond pays for the fruits is $63.
Mrs. Richmond bought some apples and pears in the ratio of 2:5. An apple costs 30 cents. A pear costs 15 cents more than an apple. How much did Mrs. Richmond pay for the fruit to determine?
What is the Ratio?
The ratio can be defined as the comparison of the fraction of one quantity towards others. e.g.- water in milk.
Here,
At first, the apple to pears ratio
(a/p) = 3/5
a = 3p/5
After giving away 3/5 apples and 40 pears the ratio become 2/5
So, apples = 1-3/5 = 2/5 ; and pear = p - 40
Ratio apples to pear,
(2/5)a/(p-40) = 2/5
2/5 * 3p/5 = 2p/5-16
6p/25 -2p/5 = -16
-4p/25 = -16
p = 100
Now a = 3/5p
a = 3/5 * 100
a = 60
Total cost of fruit = 30*a + 45*p
= 30*60+45*100
= $63
Thus, Mrs. Richmond pays for the fruits is $63.
