Answer:
g < 4 (gigabytes)
Step-by-step explanation:
Set the equation:
Total cost = (cost per gigabyte x 3) + (flat cost)
64.99 = 3g + 53
Isolate the variable, g. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS:
64.99 (-53) = 3g + 53 (-53)
64.99 - 53 = 3g
3g = 11.99
Divide 3 from both sides to isolate the variable, g:
(3g)/3 = (11.99)/3
g = 11.99/3
g = ~3.996 , or 4 when rounded.
Note: Jose wants to stay below the budget. There is a reason why it is not 4 gigabytes. If it is 4, the number will be higher than the budget allowed. This means that the inequality is:
g < 4
