Answer:
$70
Step-by-step explanation:
According to the problem, calculation of given data are as follows:
Spending money at rate = $5 per day
After 9 days money left = $25
We can calculate the money on day 0 by using following formula,
y = mx + b
Here, y = money left after 9 days
m = rate of spending money
x = number of days
b = money on day 0
So, by putting value, we get
$25 = (-5 × 9 ) + b
b = $25 + $45
= $70
No they did not bc Bradley paid less than Calvin bc if you get $90 divided by 4 it is $22.5 per shirt for Bradley but if you do $50 divided by 2 Calvin paid $25 for each shirt and then add $25 4 times bc Bradley bought 4 shirts and not 2 so get Calvin unit rate and times 4 and compare and you will see Bradley paid less for 4 shirts than Calvin
9k² = 225
k² = 225 : 9
k² = 25
k = -5 and k = 5 because :
(-5)² = (-5) * (-5) = 25
5² = 5 * 5 = 25
Answer:
- 19
- 18
- 15.5
Step-by-step explanation:
b(x) = 18 - 0.5x
b(x) = 18 - 0.5(-2)
b(x) = 18 - (-1)
b(x) = 18 + 1
b(x) = 19
b(x) = 18 - 0.5(0)
b(x) = 18
b(x) = 18 - 0.5(5)
b(x) = 18 - 2.5
b(x) = 15.5
Best of Luck!
