Answer: 4 * (12.75 + x) = 61
Step-by-step explanation:
Each of the 4 friends paid $12.75 so that is:
= 4 * 12.75
Assuming the tip is denoted as x it would be:
= 4x
Putting them together is:
4 * (12.75 + x) = 61
Solving the equation would give:
4 * (12.75 + x) = 61
51 + 4x = 61
4x = 61 - 51
x = 10/4
x = $2.50

85 multiplied by 1.20 is 102 minus 85 is equal to 17 pizzas
Ok so first, the skateboard costs $79.99. The skateboard costs 12% less with discount now so you have to pay 12% less.
You start by finding 12% of 79.99. This can be easily done by hand or with a calculator. Do 0.12 times 79.99. The answer is 9.5988. Since its 12% less we now subtract $9.5988 from $79.99. We get $70.3912. So this is the discounted price.
Now for the state sales tax. The sales tax is 6.75% which is equal to 0.0675. Like we did before, we multiplied .0675 by the value we wanted this percent of. But we can do a short way instead. Instead of getting 6.75% of $70.3912 and then adding it back to $70.3912, we can multiply $70.3912 by 1.0675 and this will do all the work for us.
So now, do $70.3912 times 1.0675 and you will have the answer. The answer is $75.142606, but wait, now we will round this to hundredths place as cents place ends their, and so the final answer will be $75.14.
