Constance is saving money to buy a new bicycle that costs $195.75. She already has $70 saved and plans to save $8 each week. How many weeks will it take her to save enough money to purchase the bicycle? It will take her weeks to save enough money to purchase the bicycle

16 weeks.

Explanation:

195.75=8x+70

Solve by subtracting 70 from both sides then dividing both sides by 8

125.75=8x
15.72=x

Meaning, if you round up it will take her approximately 16 weeks because if she only worked 15 she would be just a little bit short.

9 gallons

Step-by-step explanation:

Calculate the percentage of gas that Simon did not use this week.

10 × 0.10 = 1

Now, calculate how much he used this week.

10 - 1 = 9

Simon used 9 gallons of gas this week.
