Answer:
1) after 4 weeks, Lin has more with $65
2) after 3 weeks they both have same amount
Step-by-step explanation:
let 'w' = number of weeks
1) <u>equation for Han</u>: y = 100 - 15w
y = 100 - 15(4)
y = 100 - 60
y = $40 after 4 weeks
<u>equation for Linn</u>: y = 25 + 10w
y = 25 + 10(4)
y = 25 + 40
y = $65 after 4 weeks
2) 100 - 15w = 25 + 10w
75 - 15w = 10w
75 = 25w
w = 3 weeks
Answer:
1.85
Step-by-step explanation:
1.75-0.5+0.6= 1.85 or 1 17/20
Answer:
Water left in tank is 
gallons.
Step-by-step explanation:
Given :
Capacity of tank = 9.5 gallons 
Water taken out of tank =
gallons
We have to find the water left in the tank.
Water left in the tank = Total capacity of tank - water taken out of tank
=
Taking LCM of (3,10)= 30
Solving further, we get,
Thus, Water left in tank is gallons..
Hi there!
PART A:
The system of equations we would use would be:
x + y = 22 (amount of items)
3x + 1y = 30 (cost)
Variables:
x = the amount of strawberry wafers bought at the price of $3
y = the amount of chocolate wafers bought at the price of $1
PART B:
To solve, we'll use substitution because we can easily isolate a variable using the first equation.
Work:
x + y = 22 (first equation)
y = 22 - x (isolating a variable)
3x + 1y = 30 (second equation)
3x + (22 - x) = 30 (substituting into the second equation)
2x + 22 = 30 (simplifying)
2x = 8 (subtracting)
x = 4 strawberry wafers
4 + y = 22 (substituting x into the first equation to solve for y)
y = 18 chocolate wafers
ANSWER:
They bought 4 strawberry wafers and 18 chocolate wafers.
Hope this helps!! :)
