Answer:cost of each donut =$4
and cost of each cup of hot chocolate =$2
Step-by-step explanation:
Step 1
Let donuts be represented as d
and cups of hot chocolate be rep as c so that
5 donuts and 2 cups of hot Chocolate costing 24$ will be expressed as
5 d+ 2 c= 24
And 2 donuts and 3 cups of hot chocolate costing 14$ will be expressed as
2d +3 c= 14
Step 2
Using elimination method,Multiply equation 1 by 3 and equation 2 by 2
15d+ 6c= 72----equation 3
4d+ 6c= 28-----equation 4
Subtracting equation 4 from equation 3 gives us
11 d=44
d= 44/11
d= 4
To find c, using equation 1
5 d+ 2 c= 24
5 x 4+ 2c=24
20+2c=24
2c=24-20
2c=4
c=4/2 =2
cost of each donut =$4
and cost of each cup of hot chocolate =$2

A taxi company charges passengers $1.75 for a ride, no matter how long the ride is, and an additional $0.40 for each mile traveled. The rule c = 0.40m + 1.75 describes the relationship between the number of miles m and the total cost of the ride c.
a. What is the charge for a 1-mile ride?
b. What is the charge for a 2.7-mile ride?
A. $2.15; $2.83
B. $0.40; $5.13
C. $0.40; $1.08
D. $1.75; $2.15
Answer:
A. $2.15; $2.83
Step-by-step explanation:
2.83
c = 0.4. * 2.7 + 1.75
=> c = 2.83
4(2.7)+1.75
1.08+1.75=2.83
$2.83 is correct.
c=0.40(2.7)+1.75
c=1.08+1.75
c=2.83
Answer:
2.83 dollars
Step-by-step explanation:
Fixed charges made by the taxi company for a ride =
Additional charge for each mile travelled =
Hence equation for cost is given by
where m is thenumber of miles travelled.
To find out the charge for a 2.7 mile ride substitute m = 2.7
Total cost for 2.7 mile ride is 2.83 dollars

Answer:
Step-by-step explanation:
Slope of line passing through (x₁, y₁) and (x₂, y₂) = (y₂-y₁)/(x₂-x₁)
Slope of line passing through (9, 7) and (2, 9) = (9-7)/(2-9) = -2/7
Answer:
The slope is [tex] - \frac{2}{7} [/tex]

Step-by-step explanation:
☆Remember: [tex]m = \frac{y_2 - y_1}{x_2 - x_1} [/tex]

☆We need to find the slope . So just plug in according to the slope formula!
[tex]m = \frac{9 - 7}{2- 9} = \frac{ \: \: 2}{ - 7} = - \frac{2}{7} [/tex]

Latoya made $147 for 7 hours of work.
At the same rate, how much would she make for 9 hours of work?
help pls
Answer:
$189 in 9 hrs
Step-by-step explanation:
Division is one of the four fundamental arithmetic operations. The amount that Latoya will make by working 9 hours is $189.
What is Division?The division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.
Given that Latoya made $147 for 7 hours of work. Therefore, we can write,
Money made in an hour = Total Amount / Number of hours
= $147 / 7 hours
= $21 per hour
Now, the amount that Latoya will make in 9 hours will be,
Amount for 9 hours of work = Money made in an hour × Number of hours
= $21 per hour × 9 hours
= $189
Hence, the amount that Latoya will make by working 9 hours is $189.
