Answer:

  4 signs

Step-by-step explanation:

The total amount you spent is ...

  cash box cost + sign cost = total amount

You are told the cash box costs $10, the signs are $7 each, and the total is $38. If n is the number of signs, then the total amount is ...

  $10 + $7 × n = $38

Subtracting the cost of the cash box gives the amount you spent on signs:

  7n = 28

Dividing by 7 gives the number of signs:

  28/7 = n = 4

You bought 4 signs.

The formula for simple interest is I=Prt.
sineoko [7]

a. The formula solved for t is t = I/Pr

b. The value of t in the table is 3 years

<h3>Simple Interest</h3>

From the question, we are to solve for t in the given formula

The given formula is the formula for simple interest

I = Prt

To solve for t, we will divide both sides of the equation by Pr

That is,

I/Pr = Prt/Pr

I/Pr = t

∴ t = I/Pr

The formula solved for t is t = I/Pr

b. We are to find the value of t when

I = $75

P = $500

r = 5% = 0.05

From

t = I/Pr

t = 75/(500×0.05)

t = 75/25

t = 3 years

Hence, the value of t in the table is 3 years
