Answer:
B. 4d + 50 = 114
Step-by-step explanation:
Given parameters:
Hourly rate = $d/hr
Flat fee = $50
Charge for the 4hrs = $114
Number of hours = 4hrs
To find d;
Total cost = $114;
$114 = Flat fee + (rate per hour x number of hours)
$114 = $50 + 4d
The value of d can be calculate using;
4d + 50 = 114
The value of d is <em>4d + 50 = 114</em>
Answer:
See the three answers with their explanation below
Explanation:
<u>a. To eliminate the fraction from each side you multiply both sides by the least common denominator of the fractions of the two sides.</u>
In this case it is 2×3 = 6
See how you do it:
<u>b. This word problem would lead to the given equation:</u>
Half the age of Alice 4 years ago equals 2 more than one third of her current age.
- Current age: x
- Age four years ago: x - 4
- Half the age of Alice four years ago:
- 2 more than one third of her current age:
Equality condition:
<u>c. Solution</u>
Meaning: Alice is currently 24 years old.
So to find the number of dollars per lawn, we divide the number of lawns by the number of monies each got so
taryn mowed 9 and got 112.5 so 112.5/9= how much per lawn=12.5 per lawn
taryn charges <u>12.5 per</u> lawn
alistair mowed 7 lawns and got 122.5 so 122.5/7= how much per lawn=17.5 per lawn
alistair charges <u>17.5</u> per lawn
so taryn mowed 9 lawns in 7.5 hours and got 112.5 or 112.5 per 7.5 hours
to find how much per hour you divide 112.5 by 7.5 and get 15 dollars per hour
t=15 per hour
so we want to find out how many more hours t has to work to earn 735 more we just divide 735 by the rate (15) and find the number of hours so 735/15=49
t has to work <u>49</u> more hours to earn 735 more
Alistar=5 hours and 122.5 so 122.5/5=how much per hour=24.5
a=24.5 per hour
so we divide 735 by the rate (24.5) and get the number of hours
735/24.5=30
a has to work <u>30</u> more hours to earn 735 more
how much
