Answer:

a)

if 1 quarter = $ 0.25

  1 dime = $ 0.10

  1 penny = $ 0.01

so to make the total of $1.08 and its is also required to calculate the number of each coins present without being able to make change for a dollar

therefore we say;

1 Quarter + 8 dimes + 3 penny

: ( 1 × 0.25 ) + ( 8 × 0.10 ) + ( 3 × 0.01 )

: 0.25 + 0.80 + 0.03 = $ 1.08

b)

Now if you have a 4 Quarters, you have change for $1.

If you have 5 dimes, you have change for 2 Quarters.

If you have nickel; one of those can combine with 2 dimes to have a change for a Quarter.

If you have 5 pennies, you have enough change for 1 nickel

Therefore

(4-1)×0.25 + (5-1)×0.1 + (0×0.05) + (5-1)×0.01 = x

(3 × 0.25) + ( 4 × 0.1) + 0 + ( 4 × 0.01) = x

x = 0.75 + 0.4 + 0.04

x = $ 1.19

LuckyWell [14K]
Let

x
be the price for a pound of ham
y the price for a pound of cheese

<span>1.3x +0.8y = 11.28  ....(1)
1.5x +1.2y = 14.76  ....(2)

Lets multiply (1) by -1.2
Lets multiply (2) by 0.8

-1.56x -0.96y = -13.536 .....(3)
</span> 1.2x + 0.96y = 11.808 .....(4)


If we add (3) and (4)

-0.36x = -1.728 ............> x = 4.8

We substitute in (1)

1.3(4.8) +0.8y = 11.28

y = 6.3

Price per pound of ham = x = 4.8
Price per pound of cheese = y = 6.3

rosijanka [135]

Answer:

It will cost them $8.32 to run their dishwasher for 52 weeks.

Step-by-step explanation:

Total cost=$0.16*52

Total cost=$8.32

According to this, the answer is that it will cost them $8.32 to run their dishwasher for 52 weeks.
