Respuesta :

Answer:

He can use 1.8 gigabytes of data

Step-by-step explanation:

The equation would be:

62.90 = 57.50 + 3g

Solve:

Subtract 57.50 from both sides, which gives you:

5.4 = 3g

g = 1.8

The number of gigabytes of data that Evan can use while staying within his budget is 1.8 gigabytes.

Based on the information given, the equation to solve the question will be:

57.50 + (3 × g) = 62.90

57.50 + 3g = 62.90

Collect like terms

3g = 62.90 - 57.50

3g = 5.40

Divide both side by 3

3g/3 = 5.40/3

g = 1.80

The number of gigabytes of data that Evan can use while staying within his budget is 1.8 gigabytes.
