Rule for 1 is the rule for 1 is 14 times 3.5^x and it is exponential
The second one is is also exponential and the rule is 32 times .25^x and the last one is is linear and the rule is 5x+-4
Oh this is a great question. For future reference, the formula for this would be called an exponential growth or decay function, here it Is;
Y = a( 1+r )ˣ or Y = a( 1 - r )ˣ
the answer could be found by plugging your numbers into these equations
For example:
Y = 15,250 ( 1 - .075)⁶
A value = starting value of object
R value= decimal equivalent of percent increase or decrease
x value = number of years it has been
Answer : $9552.57
Spaghetti sauce - $2.49
Spaghetti noodles - $1.58
Gallon of milk - $3.17
$2.49 + $1.58 = $4.07
$4.07 + $3.17 = $7.24
Answer - $7.24
Hope this Helps!!
