Given:
Cost of dishwasher : 315 before sales tax
sales tax : 9.22%

Total cost = 315 * 1.0922 = 344.043

Average of 10 uses per week for the next 6 years before replacing it.
There are 52 weeks in a year.

10 uses per week * 52 weeks per year * 6 years = 3120 average uses

cost for water = 0.09 ; cost for electricity = 0.13 ; total cost per use = 0.22

0.22 * 3120 = 686.40 cost of use

purchase cost =    344.043
cost of use      =    <u>686.40</u>
lifetime cost     1,030.443

Seb bought 2 apples and 3 pears.
ryzh [129]
2a + 3p = 1.59

a = 0.24

Plug it in our equation:

2(0.24) + 3p = 1.59

Multiply:

0.48 + 3p = 1.59

Subtract 0.48 to both sides:

3p = 1.11

Divide 3 to both sides:

p = 0.37

So one pair costs <span>£0.37</span>

Step2247 [10]

Answer:

3 cups of water

Step-by-step explanation:

Henry is making a corn grits recipe that calls for 1/4 cup of corn grits for every 1/2 cup of water. How much water will he need if he uses 1 1/2 cups of corn grits?

Expand 1/2 to 2/4, if there is 1 1/2 cups of corn grits, that means that 1/4 cups of corn grits was used 6 times, 1/2x6=3. He will need 3 cups of water
