The product of a number and 3,increased by 5, is 7 less than twice the number. which equation can be used to find this number, n ?

b

step-by-step explanation:

the total is 23.97. 0.25% is off so you have to subtracting 25% from 100% and you will get 75% if you convert it to decimal you will get 0.75. you have to find the original because the formula is % times original = total.so you have the total and the % so you just have to plug it in.

so, converting firstly the mixed fractions to improper fractions and then "adding".
