The amount of money she spends per year on utility bills for the air conditioner is; D: $176.40

<h3>How to solve algebra word problems? </h3>

We are told that;

Cost of running the air conditioner = 7 hours per day

Cost of running the air conditioner = 21 cents per hour = $0.21 per hr.

She runs it for four months at 7 hours per day. Thus;

Total number of hours for the 4 months = 7 × 30 × 4 = 840 hours

Total cost for the 4 months = $0.21 per hr. × 840 hours = $176.4

Claire is saving up to buy a new laptop that costs $849. She has $232 and is saving $28 each week. How many full weeks will it t
miss Akunina [59]

Subtract the amount she has saved from the price of the laptop:

849 - 232 = 617

Now divide the amount she still needs by the amount she saves per week:

617 / 28 = 22.04

Because the answer has a number to the right of the decimal, she will need to save for 23 full weeks to have enough money.

If she saves for 22 weeks, she would be $1 short:

22 x 28 = 616 + 232 = 848

We have to consider the Order of Operations
And Divide the question into different parts
So we first do the Exponent: 2^{5} = 32
(3×32-26)=(96-26)=70
Solve the parts in parenthesis 
(8-(4-9)=(8-(-5)=(8+5)=13 (minus and minus becomes addition)
Distribute 7
7(13)=91
Now put the equation and equate everything
(3×2^{5}+13(-2))+7(8-(4-9)=70+91=161
Final Answer=161
