You want to buy three books that are on sale at 20% off. The original prices of the books are $2.50, $4.95, and $6.00. How much
Veseljchak [2.6K]

Answer:

$2.69

Step-by-step explanation:

The original prices of the books are $2.50, $4.95, and $6.00.

You want to buy three books that are on sale at 20% off (or 0.2 as decimal).

In total, you'll save:

0.2\cdot \$2.50+0.2\cdot \$4.95+0.2\cdot \$6

Uce distributive property:

0.2\cdot \$2.50+0.2\cdot \$4.95+0.2\cdot \$6\\ \\=0.2\cdot (\$2.50+\$4.95+\$6.00)\\ \\=0.2\cdot \$13.45\\ \\=\$2.69

Can someone please help me with question 3
Anastasy [175]

Answer:

8.55 inches tall

Step-by-step explanation:

equation: h = -0.75t +12. The slope is -0.75 because that's the rate of the candle burning, and the y intercept is 12 because that's how tall it is initially.

Now plug in 4.6 for t you get:

h = -0.75t + 12

h = -0.75(4.6) + 12

h = -3.45 +12

h = 8.55 inches tall
