densk [106]

Answer: $36.3

Step-by-step explanation:

Since Christopher bought 3 toy trucks that costs $14.25 each. Then, the cost of the three toys will be:

= 3 × $14.25

= $42.75

Then, if he used a coupon for 15% off of the total purchase, then the final purchase will be:

= $42.75 - (15% × $42.75)

= $42.75 - (0.15 × $42.75)

= $42.75 - $6.4125

= $36.3375

= $36.3

A photocopier increased the sides of a square in the ratio 4:5.
Svetach [21]

Answer:

The sides are increased by a percentage of 25%

Step-by-step explanation:

Let

x -----> the length side of the original square

y ----> the length side of the increased square

we have

\frac{x}{y} =\frac{4}{5}

y=\frac{5}{4}x

y=1.25x

the increase is calculated by subtracting x from y

so

y-x=1.25x-x=0.25x

Remember that

0.25=\frac{25}{100}=25\%

therefore

The sides are increased by a percentage of 25%
