Please show equation and solve for the following
1. Lyn's age is 8 years less than 15 times the age of her niece Elizabeth. If the sum of their ages is 24, what is Elizabeth's age ( Let e= Elizabeth's age)
2. Bob is renting a canoe for $20, plus $9.75 per day. How mant days did Bob rentthe canoe if he spent&78.50 altogether? (Let d = number of days Bob rented the Canoe)
Thanks
looks like you are solving
15e-8 + e = 24
and
78.75 = 9.75d + 20
what did you get?
Answer for #1 is Elizabeth is 2 and Lyn is 22
For #2 am not sure for this one, please solve
Thanks
78.50 = 9.75d + 20
78.50 - 20 = 9.75d
9.75d = 58.50
d = 58.50/9.75 = 6
so he rented the canoe for 6 days
i need help in something
Joe is 9 years older then sue.their age totals 41 .how old 8 each persob
1. Let's set up the equation to solve for Elizabeth's age (e):
Lyn's age = 15 * Elizabeth's age - 8
Lyn's age + Elizabeth's age = 24
Substituting the first equation into the second equation:
(15 * Elizabeth's age - 8) + Elizabeth's age = 24
16 * Elizabeth's age - 8 = 24
16 * Elizabeth's age = 32
Elizabeth's age = 32 / 16
Elizabeth's age = 2
Therefore, Elizabeth is 2 years old.
2. Let's set up the equation to solve for the number of days Bob rented the canoe (d):
Rent cost = $20 + ($9.75 * number of days rented)
Rent cost = $78.50
Substituting the values into the equation:
$20 + ($9.75 * d) = $78.50
Simplifying the equation:
$9.75 * d = $78.50 - $20
$9.75 * d = $58.50
Dividing both sides of the equation by $9.75 to solve for d:
d = $58.50 / $9.75
d = 6
Therefore, Bob rented the canoe for 6 days.
