45 times 1.065=47.925 which would be $47.93... hope that helps
Answer:
a. No
b. 2.25 days
Step-by-step explanation:
0.75x + 3 = 0.25x + 5.25
a......................
Constants are $3 and $5.25 respectively
Topping costs $0.75 and $0.25 respectively
To have same cost the toppings number would be different as cost is different.
Suppose the number of toppings is x in one shop and y in the other, then the spending if same, we get this equation:
The answer is NO due to two different variables in the equation
b.......................
Constants are $3 and $5.25 respectively
Joseph adds $0.75 each day and Kelsey spends $0.25 each day
Number of days should be same in this case, so variable will be same and the result (amount left in bank) is same.
<u>So the equation for this case is:</u>
<u>Solving, we get:</u>
- 0.75x + 0.25x = 5.25 - 3
- x = 2.25
This is the solution to equation despite being a whole number.

Answer:
the desired equation is y = (2/3)x - 2/3
Step-by-step explanation:
As we go from (1/2, -1/3) to (2,2/3), x increases by 3/2 and y increases by 1. Hence, the slope of this line is m = rise / run = 1/(3/2), or 2/3.
Use the slope-intercept form of the equation of a straight line, y = mx + b:
Substituting 2/3 for y, 2 for x and 2/3 for m, we get:
2/3 = 2(2/3) + b.
Clear out the fractions by multiplying all three terms by 3:
2 = 4 + 3b, or -2 = 3b, or b = -2/3.
Then the desired equation is y = (2/3)x - 2/3
