It is a week before the maths festival. a maths exhibitor costs £75.40 and so far 12 have been bought. what is the total income so far?

Total income would be  £ 904.8

Step-by-step explanation:

Given,

One exhibitor's cost =  £ 75.40

Also, 12 have been bought,

That is, the total number of exhibitors = 12,

Thus, the total income after buying the exhibitors = One exhibitor's cost × Total exhibitors bought

= £ 904.8

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.
