Lemme give you a cheap answer, by simply using the "compound interest formula", which is what that is, 2% compounded yearly
thus
plug in those values, and simplify
Answer:
Step-by-step explanation:
We have 2 linear equations, and in both, the amount of merchandise you would have to purchase is "x", the unknown. We are asked to find that value of x.
The first equation is
C(x) = .30x + 90, which says that the cost of this plan is a fixed $90, and you pay 30% of the manufacturer's cost, x.
The second equation is
C(x) = .80x + 40, which says that the cost of this plan is a fixed $40, and you pay 80% of the manufacturer's cost, x.
If we want to know when the cost of these 2 are equal to each other, we set the equations equal to each other and solve for x:
.3x + 90 = .8x + 40 so
-.5x = -50 so
x = $100
The cost for each plan will be the same at this value of x, but we will plug in 100 for x in each just to make sure we did it right:
C(100) = .3(100) + 90
C(100) = 30 + 90
C(100) = 120 and
C(100) = .8(100) + 40
C(100) = 80 + 40
C(100) = 120
So we can do this by finding how much is needed for one pancake first.
50ml of milk is needed to make 1 pancake.
From there we can multiply it by 6 to figure out how much we need for 6.
Alternatively, you can just divide 400 by 8/6 but some people find that confusing and it's often easier to follow workings if you do the above method.
300ml of milk is needed to make 6 pankakes.
Answer:
Fraction: 8
Decimal: 8.55
Step-by-step explanation:
8 11/20 is the answer because:
1) Since 8 is the whole number, 8 wouldn't be part of the fraction
2) The numerator is the top number in the fraction, so 11 is at the top since 11 is the numerator
3) The denominator is the bottom number in the fraction, so 20 is at the top since 20 is the denominator
8.55 is the answer because:
1) Since 8 is the whole number, 8 would be in front of the decimal point
2) When you multiply the fractions, you have to multiply until you get a hundred. Therefore, 20*5 = 100 and 11*5 = 55
Hope this helps!
