Hotel a cause 40 x 4 = 160 which is under 175
You literally just multiply 15*4 which is 60 slices ☠️
20 + (0.4 × 15) + 12 + (0.4 × 10) = 20 + 6 + 12 + 4 = 42
20 + 15 + 12 + 10 = 57
57 - 42 = 15
15 ÷ 57 × 100 = 1500 ÷ 57 = 26.3
Ans = $42.00, 26% off ...
I don’t understand the equation but you can use Photomath to solve any equation you need to solve. It’s and app for free.
Number is n
Three times the sum of a number and 4.
= 3* ( n + 4) = 18
3n + 12 = 18.
3n = 18 - 12.
3n = 6
n = 6 / 3.
n = 2.
