Answer:
one glass of milk = 15 carbs
one bar = 14 carbs
Step-by-step explanation:
let 'm' = one glass of milk
let 'b' = one snack bar
system of equations:
2m + 3b = 72
4m + 2b = 88
I used the elimination method and multiplied the 1st equation by -2
-4m - 6b = -144
+ <u>4m + 2b = 88</u>
-4b = -56
b = 14
now solve for 'm'
2m + 3(14) = 72
2m + 42 = 72
2m = 30
m = 15
Let, the cost of 1 piece of fudge = x
Cost of a gum = y
System of equations: 5x + 3y = 5.70
2x + 10y = 3.60
Multiply 1st equation by 2, and second by 5,
New equations: 10x + 6y = 11.40
10x + 50y = 18
Now, subtract 1st from 2nd,
44y = 6.60
y = 6.60 / 44
y = 0.15
Substitute it in second equation,
2x + 10(0.15) = 3.60
2x = 3.60 - 1.5
x = 2.10 / 2
x = 1.05
In short, Cost of a Fudge = $1.05 & Cost of a gum = $0.15
Hope this helps!
Answer:
Step-by-step explanation:
Amount paid for first 100 watches = (65% of 80) *100
Amount paid for next 50 watches = (55% of 80) * 50
Remaining watches = 280 -(100+ 55)
= 280 - 155 = 125
Amount paid for 125 watches = (45% of 80) *125
Amount received by the watch maker = 5200 + 2200 + 4500
= £ 11900
