The formula for the circumference is:

So to find first radius:

Second radius:

The ratio between them is:
5x + 34 = -2(1 - 7x)
5x + 34 = -2 + 14x
36 = 9x
x = 4
NO = -2(1 - 7*4)
NO = -2(1 - 28)
NO = -2 + 56
NO = 54
You can make an equation: 6.75 + x = 10
6.75 is the amount you spend on the book, x is the amount you can spend on the drink, and 10 is the total cost.
Solve for x to find how much you can spend on the drink.
6.75 + x = 10
Subtract 6.75 from both sides to isolate x.
x = 3.25
You can spend $3.25 on the drink.
.75x+1.29y < $7.00
x represents how many bagels he can buy
y represents how many cream cheese containers he can buy
