Answer:
She has been a member of the gym for seven months
Step-by-step explanation:
In this question, we are asked to calculate the number of months a customer has been a member of a gym, given the pricing template of the gym.
Now, as we can see from the question, there are two kinds of fees to be paid. The flat fee and the subscript class.
First, let’s represent the number of months she has been a member of the gym by m. This means the total amount of money she has paid for m months would be m * 19.99m
Now, recall, we have a flat fee of $68, adding this to the total monthly payment for m months bring the wages to 19.99m + 68
This is said to equal $207.93
This means;
19.99m + 68 = 207.93
19.99m = 207.93 -68
19.99m = 139.93
m = 139.93/19.99 = 7
Hi!
We know the amount needed to make 8 pancakes. Dan wants to make 12 pancakes. 12/8 = 1,5, that's the ratio, we need to multiply each ingredient with 1.5 and we will get the amount needed to make 12 pancakes.
240 * 1,5 = 360 g of plain flour
2 * 1,5 = 3 eggs
600 * 1,5 = 900 ml of milk
Hope this helps!
