Answer:
The first one
Step-by-step explanation:
To figure out which one is the best deal, for each one how much <em>one</em> t-shirt costs.
<u>First deal:</u>
3 t-shirts for $28.95
To figure out how much money one t-shirt would cost, you divide $28.95 by 3.
1 t-shirt = 28.95/3 = $9.65.
<u>Second deal:</u>
4 t-shirts for $39
Same thing as the last one, except since there are 4 t-shirts you divide $39 by 4.
1 t-shirt = 39/4 = $9.75
<u>Third deal:</u>
5 t-shirts for $49.95
This time you will divide 49.95 by 5.
1 t-shirt = 49.95/5 = $9.99
The last step is to compare the three deals, and since you are trying to find the one that costs the <em>least</em> you can see that the first deal is the best one, because $9.65 per shirt is cheaper than $9.75 and $9.99

Answer:
The percentage increase in Tessa's stock is 40%
Step-by-step explanation:
Given that:
Previous worth = $173
Worth now = $242.20
We have to find percentage increase which can be known by subtracting previous worth from present worth and multiplying it by 100:
Percentage increase = $242.20 - $173 = $69.2
Percentage increase = $69.2/173 *100
Percentage increase = 40%
i hope it will help you!
Answer:
The slope is apperently 5 and i rlly don't have a step-to-step explaintion but my teacher explained it and said it was 5 slopes.
Step-by-step explanation:
Answer:
y = 2x + 0
Step-by-step explanation:
the formula is y = mx + b
m = slope = change in y/change in x = (84 - 76)/(42 - 38) = 2
Slope is 2.
b is the y-intercept, which is the coordinate when x = 0. To find b, substitute any coordinate from the table. Let's use (38, 76)
y = 2x + b
76 = 2(38) + b
76 = 76 + b
b = 0
So the equation is y = 2x + 0
