Cooper and his children went into a bakery and where they sell cupcakes for $2.50 each and donuts for $1.50 each. Cooper has $40 to spend and must buy a minimum of 18 cupcakes and donuts altogether. If Cooper decided to buy 7 cupcakes, determine the maximum number of donuts that he could buy.

15

15

7 cupcakes=17.5

40-17.5=22.5

donuts are 1.50

22.5 divided by 1.5 is 15

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

an = 22 + (n-1) *6

110 seats

step-by-step explanation:

an=a1+(n-1)(d)

a1 = 22   this is the first item in the sequence

d =6   this is how the sequence goes up

a)   an = 22 + (n-1) *6

b) a12 = 22 + (12-1) *6

    a12 = 22+11*6

  a12 = 22 +88

  a12 = 110
