Answer: If the 40% off coupon is used, the subtotal will be $12.69

The gratuity would be exactly $4.23 (He will probably leave $4.25)

Step-by-step explanation: To find out the amount of the discount

.40 × 21.15 = 8.46

To find the new subtotal, subtract 12.15 - 8.46 = 12.69

To figure the tip: .20 × 21.15 = 4.23

Changing the percent to a decimal means divide the 20 by 100.

What is the value of the expression

Y_Kistochka [10]

Answer:

0.8

Step-by-step explanation:

We begin with the expression: $0.5+(-\frac{3}{4} )+0.25-(-\frac{4}{5} )$

First, we need to convert the fractions into decimals to make this easier.

$-\frac{3}{4}=-0.75$ and $-\frac{4}{5} =-0.8$

Once we have this, we can simplify it

$0.5-0.75+0.25-(-0.8)\\\\0.5-0.75+0.25+0.8\\\\0.75-0.75+0.8\\\\0.8$
