Answer:
Yes, we have enough money to pay for the groceries.
Step-by-step explanation:
We are given that Groceries cost $75. The tax rate is 5%.
We have to check that will the amount of $80 enough to pay for the groceries or not.
<em>For this we will firstly calculate the total cost of groceries after applying tax rate of 5% on groceries. </em>

Therefore, yes we have enough money to pay for the groceries.

Answer:
y = -3/7x + 5
Step-by-step explanation:
y2 - y1 / x2 - x1
2 - 8 / 7 - (-7)
-6/14
= -3/7
y = -3/7x + b
2 = -3/7(7) + b
2 = -3 + b
5 = b
Answer:
0.74
Step-by-step explanation:
We can isolate x, getting 9.2x - 1.9x = -1 + 6.4
We can then simplify, getting 7.3x = 5.4, which we can solve by dividing both sides by 7.3:
x = 5.4 / 7.3 = 0.74
