The equation 9.95 + 0.30s= c gives the cost c in dollars that a website charges for downloading songs. The variable s stands for the number of songs downloaded. Find the cost of downloading 35 songs.
To find the cost of downloading 35 songs, substitute s = 35 into the equation 9.95 + 0.30s = c and solve for c.
9.95 + 0.30(35) = c
9.95 + 10.50 = c
20.45 = c
Therefore, the cost of downloading 35 songs is $20.45.
9.95 + 0.30(35) = c
9.95 + 10.50 = c
20.45 = c
Therefore, the cost of downloading 35 songs is $20.45.
You have $27 to spend at the mall and a coupon for $6 off at your favorite store. A t-shirt costs $11. How many t-shirts can you buy using your coupon and money?
To calculate how many t-shirts you can buy, let's begin by subtracting the coupon amount from the total amount you have to spend: $27 - $6 = $21.
Now, divide the remaining amount you have to spend by the cost of each t-shirt: $21 ÷ $11 = 1.909.
Since you cannot purchase a fraction of a t-shirt, you can only buy 1 t-shirt with your coupon and money.
Now, divide the remaining amount you have to spend by the cost of each t-shirt: $21 ÷ $11 = 1.909.
Since you cannot purchase a fraction of a t-shirt, you can only buy 1 t-shirt with your coupon and money.
