Question

для ремонта квартиры купили 8 рулонов мастерской сшили 120 спальных мешков за 6 дней, одинаковое количество мешков в каждый день. За сколько дней сошьют 100 спальных мешков ,если ежедневно будут шить на 5 мешков больше?

Answer 1

To solve this problem, we can use the concept of ratios and proportions. Let's break down the information given:

- 8 rolls of fabric were purchased for the apartment renovation. - In 6 days, 120 bed bags were sewn, with the same number of bags sewn each day. - We need to determine how many days it will take to sew 100 bed bags if each day they sew 5 more bags than the previous day.

Step 1: Calculate the number of bed bags sewn per day

To find out how many bed bags were sewn each day, we can divide the total number of bed bags sewn (120) by the number of days (6): 120 bed bags / 6 days = 20 bed bags per day

Step 2: Calculate the number of bed bags sewn on the last day

Since the number of bed bags sewn each day increases by 5, we can calculate the number of bed bags sewn on the last day by adding 5 to the number sewn per day: 20 bed bags per day + 5 = 25 bed bags on the last day

Step 3: Calculate the number of days needed to sew 100 bed bags

To find out how many days it will take to sew 100 bed bags, we can set up a proportion using the number of bed bags sewn per day: 20 bed bags per day = 100 bed bags / x days

To solve for x, we can cross-multiply and solve for x: 20x = 100 * 1 20x = 100 x = 100 / 20 x = 5

Therefore, it will take 5 days to sew 100 bed bags if each day they sew 5 more bags than the previous day.
