23x3 is 69
219x6 is 1314
840x 3 2520
The tax added to $220 is solved by 220 X .0725 = 15.95. Add 15.95 to $220 and get $235.95. The tip (assuming it is 20% after tax ) is $235.95 X .20= $47.19
Add the $47.19 to $235.95= $283.14
Answer:
30 *im not completely sure*
Step-by-step explanation:
First set up the ratio 2/5 = 10/x where <em>x</em> is the number of girls.
Now, we can use cross-products to find the missing value.
So we have (2)(x) = (5)(10).
Simplifying, we have 2x = 50.
Dividing both sides by 2, we find that x = 25.
So there are 25 girls in the class if there are 10 boys.
285 is the answer. 190÷4=47.5
47.5×6=285
