Step-by-step explanation:
we know that
Emilio cay type 850 words in 17 minutes
Remember that
so
using proportion
Find out how many words can Emilio type in 60 minutes (one hour)
Let
x ---> the number of words
Solution
Provided :-
• I have $138
• I save $12 per week
• Friend have $ 98
• He saves $17 per week
Let the number of weeks required to have same balance be x
→ 138 + 12x = 98 + 17x
→ 138 - 98 = 17x - 12x
→ 40 = 5x
→ x = 8
So we need 8 weeks
