Which of the following expressions could be used to find the sale price of an item that costs d dollars if it is on sale for 30%

Elenna [48]

Greetings!

An item at full price is 100%, or by using the percentage formula: $(\frac{percentage}{100})$

If something is at 30% off, that means it is 70% of the original price (because minus the percentage from the 100%)

So by substituting the numbers into the percentage formula you end up with:

$(\frac{70}{100})$ which is 0.7

So your answer would be D, 0.7!

Hope this helps!

A Bank offers an annual simple interest rate of 8% on home improvement loans. Tobias borrowed $17,000 over a period of 2 years.

Alex17521 [72]

We first find out the amount in dollars of interest accrued after 2 years time.

Interest = Prt

where P is the principal, r is the rate and t is time

8% written in decimal fraction → 8/100 → 0.08

Interest = 17000 × 8% × 2

Interest = 1700 × 0.08 × 2

Interest = 2,720 dollars

We add the principal and the interest to get full amount paid, so:

17000 + 2,720 = 19,720

I hope that you good day

write and solve an equation to show thw average number of calendars her 3rd period class sold peer week during the four week cha

kari74 [83]

If they sold 89 calendars over 4 weeks, the 'equation' would look like (x = average calendars sold over 4 weeks):
$x = \frac{89}{4}$

If you solve it, you get:
$22 \frac{1}{4}$

Which is equal to 22.25. Hope this helps!
