Tanya would be 14 because jassica is 5 and 5x3=15-1=14
If you would like to evaluate the expression d - 15 when d = -23, you can calculate this using the following steps:
d - 15 = (-23) - 15 = - 23 - 15 = -38
The correct result would be -38.
Set up a proportion.
Let x = cost for 1 pound.
6.75/x = (3/4)/1
(3/4)x = 6.75
x = 6.75 ÷ (3/4)
x = 6.75 ÷ 0.75
x = 9
The price for 3/4 pounds of fudge is $6.75.
For one pound, the price is $9.
