$60/l
5 more liters of fuel
total cost 25 x .60 = $15
Answer:
3.4 pizzas
Step-by-step explanation:
Given is a scatter plot showing number of pizzas sold during weeks for different issues of coupon
y represents number of pizzas sold and x number of coupons issued
y is marked verticaly and x horizontally
The trend line is given as
y =3.4x+43
This says that even when no coupon is issued pizzas sold will be 43
and rate of change of pizza sold for 1 unit of coupon = slope = 3.4
i.e. when x increases by 1 unit y increases by 3.4 units
Hence For each additional coupon issued 3.4 pizzas more will be sold
Answer:
10058
Step-by-step explanation:
The equation is of the form
y = ab^x
Where a is the initial value, y is the final amount and x is the time
y = 6000 b^x
7200 = 6000 b^6
Divide each side by 6000
7200/6000 = b^6
1.2 = b^6
Take the 6th root on each side
1.2 ^ 1/6 = b^6 ^ 1/6
1.030853321 = b
y = 6000 (1.030853321) ^ x
Let x = 17
y = 6000 (1.030853321) ^ 17
y=10057.68696
Rounding to the nearest whole number
y = 10058
