Answer:
Mom === 10.25
Daughter === 3.25
Step-by-step explanation:
Let’s the mom age be 7+x and the daughters age be x. Put it in a linear equation 7+x=5(4+x).
open the bracket which will give you 7+x=20+5x.
collect like terms which will give you 5x-x=20–7 and you will get 4x=13 where x is 3.25 the mom is 10.25 and the daughters age is 3.25
Let the number of nickels be n, then the number of quarters is 84-n.
The value of 1 qtr is 25c and the value of 1 nickel is 5c.
The total value is 5n+25(84-n)=1240 (in cents).
5n+2100-25n=1240, 20n=860, n=860/20=43.
So there are 43 nickels (worth $2.15) and 41 quarters (worth $10.25).
