Answer:
Helmets-12
Baseballs-32
Step-by-step explanation:
Given the tax rate as 6% and the reduced prices as $2.25/baseball and $22.50/helmet and that the budget is $400:
The new prices are reduced price plus tax:
Let x be the number of groups of 8 baseballs as well as the number of groups of 3 helmets,therefore:
Substitute for x=4 to find the highest number of baseballs and helmets:
Helmets=4x3=12
Baseball=4x8=32
#Price cost will be 12x23.85+32x2.39=362.68 (balance=37.32)
Hence, Shaw can buy 12 helmets and 32 baseballs and still remain with $37.32

Divide each value
Hmmm......
Then, you must be thinking of 19.
Explanation:
Let you numher be x
now
according to question
multiply it by 8 and it becomes 8×x = 8x
Now add 22
so it becomes
8x + 22
now as told in the question take the same number again i.e x for one more time.
multiply it by 6
and you'll get 6x
and after adding 60 you'll get 6x + 60
Now again according to question
8x+ 22 and 6x+60 are same number therefore they must be equal,
8x+22 = 6x+60
Do a little azebra
8x -6x = 60 -22
2x = 38
x = 19.
and Tada, your number is here.
Answer:
The function best describe the linear relationship be y = 640 - 75x.
Step-by-step explanation:
As given
Wanda has $640 in her checking account.
She pays her landlord $75 per week for rent.
Let us assume that the number of weeks be x.
Let us assume that the y reresented the money in the account after x weeks.
Than the function becomes
y = 640 - 75x
Therefore the function best describe the linear relationship be y = 640 - 75x.
