Ed spent 8.5% of his savings on lunch, which cost $5.25. How much did he have in his savings before lunch?

Lunch cost =$5.25

percentage spent =8.5%

1%of saving =$0.617

total amount =100×0.617

=$61.76

62.94117

Step-by-step explanation:

100/100 ×8.5×saving=100×5.25

But 100/100=1

8.5×savings=535.00= 62.94117

= 5

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5
