Mary wants to buy a new tennis racket that cost $57.50. She has $8 and plans to save $4.50 each week. How many weeks will it take her to save the money? * 24 weeks
15 weeks
11 weeks
10 weeks

11 weeks

Step-by-step explanation:

57.5=8+4.5x

49.5=4.5x

11 = x

hello 0xxbadwolfxx0,

2.6 x 10^9 is 2,600,000,000.

1.3 x 10^2 is 130

multiplying 130 and 2,600,000,000 would simply give you 200,000,000,000.

therefore, the answer would be d. 2.0 × 10^11.

i hope i ! warm regards, mae.
