Answer:
y=0x-1
Step-by-step explanation:
y=0(x)+c
-1=0(7)+c
-1=0+c
C=-1
For this case, the first thing we must do is define a variable.
We have then:
n: number of days.
We now write the explicit formula that represents the problem.
We have then:
an = 4n + 15
Where,
15: crunches the first day
4: increase the number 4 each day
Answer:
An explicit formula for the number of crunches Abbie will do on day n is:
an = 4n + 15
2g + 4h = 43
2g + 2h = 30
2h = 13
h = 6.5
2g + 26 = 43
2g = 17
g = 8.5
1 glove is $8.50 and 1 hat is $6.50
